question 20 of 20
which statement describes how electrical power is calculated?
a. power is the product of voltage and current.
b. power equals current divided by voltage.
c. power is the product of current and resistance.
d. power equals voltage divided by current.

Explanation:

The formula for electrical power is \(P = VI\), where \(P\) is power, \(V\) is voltage, and \(I\) is current. This means power is calculated as the product of voltage and current.

Answer:

A. Power is the product of voltage and current.
