Before working on any motor, be sure you discharge the capacitor. Capacitors store energy and can pack a serious and potentially dangerous jolt of electricity.
This will explain how to add a car audio capacitor for your mobile audio system.
Don't be intimidated by this large and mysterious appliance. There are some parts you can work on yourself if you're mechanically inclined - and even if you can't fix it yourself, it's good to...
Electronics hobbyists work with many different types of circuits. For those that work with digital electronics, a power supply of 5V DC is required to drive the circuit components. Building a...
A radio provides signal transmission via the use of electromagnetic waves. The frequencies a radio uses are lower than those of visible light. A German scientist by the name of Heinrich Hertz was...
Learn how to solder a capacitor to a circuit board in this free video.
Testing and troubleshooting electric motors can seem to be a magical art form if you do not know some simple steps.
Testing the starting capacitor on a motor is a good first step to getting a motor to run. In fact, replacing a capacitor is not difficult. This is why knowing how to replace the capacitor is...
How to keep from injuring themselves as capacitors can be fatal if handled wrong
Ok, so your swimming pool motor stopped running and will not start. All it does is buzz, or smoke...or does nothing. Well it's fairly easy to figure out if it's fixable or not with a little...
Five basic electrical symbols tend to show up in electrical diagrams or schematics. By referring to the included image, you can match these to their definitions.

Capacitors come in many sizes and can be found in a wide variety of electrical devices. Their sole purpose is to store energy for a temporary period of time, but if they are removed from the power...
A passive crossover filters out lowpass or highpass frequencies from reaching midrange, midbass and tweeter speakers. Applying one to your car stereo system may improve the clarity and power of...
A capacitor is a pair of conductors (plates) separated by an insulator (dielectric) that has capacity of storing an electric charge. A capacitor is frequently used in electronic circuits to...
A capacitor stores an electrical charge between two conductors (plates) separated by an insulator (dielectric). This is similar to a battery, although a capacitor is used only for temporary...
These days it pays to protect yourself. Unfortunately, it is not always safe to walk by yourself at night, and sometimes having something to protect yourself can make a world of difference. With...
The start capacitor on a washing machine motor gets the motor up to speed quickly before transferring power to the run capacitor. When the start capacitor fails, the temptation is to replace the...
You wake up to find yourself held hostage in the dark damp storage room of an abandoned warehouse. The guard at the door will be back to check on you shortly and the only thing you have at your...
A variable capacitor is not a familiar term to most. No, it's not a device that makes time travel possible. It does come in handy, however, when you want to build a radio. By following this...
A tattoo machine's base or "gun" houses the mechanism and the sanitary tube. The mechanism contains two coils of wire wrapped around an iron core and a capacitor between them. The machine moves...
There are many reasons to want portable power, including a backup for power outages, camping or just because you like to tinker. Using the pedal power from an old bike is a great way to generate...
Learn how to store a charge in a capacitor in this free home maintenance video.
If you've ever watched an old science-fiction movie, you're probably familiar with a Tesla coil. Invented by Nikola Tesla late in the nineteenth century, a Tesla coil is a device that can generate...
A capacitor relies on the electric field produced when electrically conductive plates are placed near each other without touching. This phenomenon occurs because air does not permit current to...
A capacitor usually consists of two conductors placed close to each other. It stores electrical charge in units that are called a farad. Common capacitor values typically range from picofarads to...
In recent years the stun gun has become a safer, more legal and less fatal form of self protection. There are numerous brands and models of stun guns on the market today, some of which are used by...
Bioengineering covers a broad spectrum of research and development fields such as, biomechanics, biomaterials, and bioelectric engineering. Understanding the properties and mechanism of the...
The generator is the most important part of the shake flashlight. It consists of a hollow copper coil with a permanent magnet inside of it. The permanent magnet is in a track which allows it to...
The term "computer memory" often refers to RAM, or random access memory. RAM is the most common form of computer memory used in desktop and laptop computers. RAM stores data temporarily (rather...
Farm duty electrical motors most often consist of split-phase induction motors designed for heavy duty assignments. As split-phase motors use a separate starter winding, these require a capacitor...
AC motors are normally long lasting and dependable. Motors often operate for years in dusty and dirty environments. Most motors are normally mounted out of sight, so they often do not get serviced...
Removing rats from your home or office? Eliminating rodents with traps and poisons can often leave injured or dead animals within crawlspaces and walls. Even when the traps are successful, the...
Troubleshooting a farm duty electrical motor can be a fairly straightforward and reasonably swift process, as long as you understand what you are doing, where to look and what kind of equipment to...
An assembled tattoo gun includes a variety of parts, including the power coils, the capacitor, the armature bar, the barrel and the needle. Correctly assemble a tattoo machine with instructions...
Building a circuit is a fun and exciting experience, and it comes with a strong sense of accomplishment. However, there are often a lot of variables to consider. For example, when you have an...
A tank circuit is an electronic circuit used in many applications, including oscillators, TV and radio sets. In it's most basic form, the circuit consists of just two electronic components, namely...
A digital multimeter is a device used to measure various properties of electricity, from voltage and current to capacitance frequency. In fact, many people may never use a digital multimeter for...
A Taser is a piece of equipment that creates a temporary state of partial or full paralysis by delivering an electrical shock that disrupts voluntary muscle control. Tasers are legal and in most...
A time delay circuit is a programmable circuit that provides a delay in signal between your input source and output message. Time delays are used in everything from audio electronics to security...
DSL data connections are carried on the same phone lines as voice communications but operate at non-overlapping frequencies. When data and voice are carried on the same phone line at the same...
A capacitor is an electronic component which, in combination with other components in a circuit, can be used for many purposes, from storing electricity, filtering power supplies and blocking...
A capacitor serves an important function in a car audio system. The capacitor stores electrical energy that can be rapidly added into the system when power demands become to great for the...
A capacitor is a device for storing a small electric charge. When two conductive plates are separated by a small insulator called a dielectric, they produce an electric field. The strength of this...
