Hello my name is Mark Blocker and in this segment I'm going to cover what is a volt. What a volt is is a unit of measurement used to measure electricity primarily electromotive force and it would be real difficult to explain what an electromotive force is in a short period of time so I will try and point out how it effects or kind of pertains to us. In house current or your house usage voltage is measured in AC and it is usually found in common household receptacles and it has somewhere between 115 and roughly 120 volts give or take a few. That depends on the stability of the transformers provided by your local power company and the loads applied to the circuit. Here I have a bolt meter connected to a standard home extension unit and you can see it is reading about 122 volts roughly. So a volt is a unit of measurement used to measure electromotive force. That's what a volt is.
