Which symbol is commonly used to denote electrical power in the equations?

Explanation:
Power in electrical circuits is represented by the symbol P. This is the standard notation used in formulas such as P = VI, showing power as voltage times current, and also P = I^2R or P = V^2/R for resistive elements. The other symbols denote different quantities: I is current, V is voltage, and R is resistance. So the symbol P is used specifically for power, which is why it is the correct choice in these equations.
