5. One watt of electrical power is produced when
A. one ampere of current flows due to an applied voltage of one volt.
B. work is done to move electrons with respect to time.
C. electrical pressure is present in a circuit.
D. a conducting path is present between two opposing electrical charges.

Correct answer is A

Explanation:

one ampere of current flows due to an applied voltage of one volt

Because

One watt is the rate at which work is done when a current of one ampere, I of current flows through a network which has an electrical potential difference of one volt

Also

power is defined as the rate of doing work

P=V .Q/t

But as

Q/t=Current, I

Substituting:

P=V I

where P = Power in watts

V= volts

I = Current
