Connecting batteries in a series is a way to multiply the voltage of the batteries while maintaining their given capacity. For example, five 9-volt batteries connected in series will produce 45 volts of power. Using 9-volt batteries in series is a good technique to employ when your application requires a higher voltage equal to a multiple of 9, such as a trolling motor for a fishing boat. more »

Dry cell batteries are batteries that use an extremely low-moisture electrolyte. They are contrasted by wet cell batteries such as lead-acid batteries, which use a liquid electrolyte. The electrolyte that is used in most dry cell batteries is a sort of paste which, though containing moisture, is still relatively dry. The most commonly used forms of dry cell battery are "C" batteries, "A" batteries, 9-volt batteries, and watch batteries. more »
One of the most significant ways to improve the tone of an electric guitar is to replace the pickups. For this example, an EMG 89R will be installed at the neck position and an EMG 85 at the bridge, connected by a 3-way blade switch. The EMG 89R will be wired to a push-pull switch on the volume control. This will be used to switch the pickup between single coil and humbucking modes. The circuit will be powered by two 9 volt batteries wired in series, to make it 18 volts. more »
Smoke detectors for home use can usually be divided into two types. These are ionization detectors and photoelectric detectors. If you have a smoke alarm in your home, chances are it is one of the two, and possibly even a combination of both. They may use these sensors in addition to a heat detector to warn the resident when there is an alarming amount of smoke in the home, possibly indicating a fire. These alarms may use a 9 volt battery, or the home's electrical wiring in order to function. more »
LED lights use very little power and emit a bright light.
