For example, in a battery, one type of energy is converted in another kind of energy when the electric charges are transferred within the device itself. Electromotive force is usually measured in volts. 1 Volt is equal to 1 joule per coulomb of electric charge. Its formula is electromotive force. W = work done when charges are moved, and C= electric charge. E=W/C Explain the differences between conductors and insulators Conductors are materials that permit electrons to flow freely from one particle to another. For example, metals are good conductors and copper is widely used across the globe. On the other hand, insulators are materials that impede the movement of electrons from one particle to another. For example, some kinds of plastic are good insulators, and they are used where electric current is not needed. Accurrent of I mA flows for T minutes through the filament of a car headlamp bulb.
