Electric potential symbol phi
WebThe electromotive force or EMF refers to the potential difference across the unloaded loop (i.e. when the resistance in the circuit is high). In practice it is often sufficient to think of EMF as voltage since both voltage and EMF … WebBasically electric potential is defined as the work done in moving a point charge from one point to another point under a constant electric field, and we find the formula to be V=W/Q V = W /Q. Motivation decided: Energy …
