Question

Select the statement that shows the correct relationship between current, voltage, and power.

A decrease in power will occur if current is increased and voltage remains the same.

An increase in voltage, with no change in current, will result in an increase in power.

In order to increase power, there must be a decrease in either current or voltage.

The only way to decrease current is to decrease power.

I think it's D but maybe I'm confused.

Answer 1

What is the formula relating power with current and voltage?

Answer 2

So it's b?

Answer 3

Yes
P = VI

Hence b is true and each of the other options are false.

Answer 4

Thanks.
