What is the symbol for voltage?

A. p

B. V

C. I

D. v

Ohm's law equation (formula) : V = I * R and the power law equation (formula) : P = I * V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).

the answer is b. v

The symbol for Volts (Voltage) is V.
