Which circuits correctly show ohm’s law?

Ohm’s Law:

V = IR

V = battery voltage, I = current, R = resistance

V = 25V, I = 5A, R = 5ohm

25 = 5•5

25 = 25

This circuit is correct.

V = 18V, I = 6A, R = 4ohm

18 = 6•4

18 =/= 24

This circuit is incorrect.

V = 56V, I = 7A, R = 8ohm

56 = 7•8

56 = 56

This circuit is correct.

V = 20V, I = 5A, R = 4ohm

20 = 5•4

20 = 20

This circuit is correct.
