Power is represented by which symbol?

Explanation:
Power is the rate at which energy is transferred or work is done, and the standard symbol for this quantity is P. This appears in key electric-power formulas like P = VI, P = I^2R, and P = V^2/R, where P specifically denotes power. The other symbols correspond to different quantities: E stands for energy (or electromotive force in some contexts), V stands for voltage, and I stands for current. So P is the conventional symbol used to represent power in these relationships.
