Question

If a 10.0 kW device pulls 20.0 A of current, what voltage exists across it?

A. 5.0 *10^0 V

B. 5.0 *10^1 V

C. 5.0 *10^2 V

D. 5.0 *10^3 V <---

Answer 1

Power = VI, compatible units are W, V, A.

10 kW = V(20 A)

NOTE: 10 kW = 10000 W

Answer 2

10x10^3 W
10,000/ 2A
= 5000
which would be D right?

Answer 3

i mean its, C :)
10,000/ 20 A
= 500

Answer 4

That's correct!
