Respuesta :
Answer;
A. P = E2/R
Explanation;
Based on the context of electricity the formula for power is given by
P = E2/R; where
P is power in Watts;
I is current in Amps;
R is resistance in Ohms; and
E is voltage in Volts.
The formula may also be given as P = V2/R
Answer:
The correct answer is A.
Explanation:
P = E²/R shows that the power in a circuit is the square of applied voltage applied and inversely with the circuit resistance. This expression is extension of OHM'S law.
