Question

question 3 of 25
what is the relationship between voltage and power in a circuit?
a. in a circuit, voltage and power are unrelated.
b. in a circuit, voltage and power remain equal.
c. increasing the voltage in a circuit increases its power.
d. increasing the voltage in a circuit decreases its power.

Explanation:

The power formula in an electrical - circuit is $P = VI$ (where $P$ is power, $V$ is voltage, and $I$ is current). Assuming the current remains constant, when the voltage $V$ increases, the power $P$ also increases.

Answer:

C. Increasing the voltage in a circuit increases its power
