what is the correct calculation for voltage of the resistance is three ohms in the current is 4 A

Question

a 4÷3 = 1.33 V
b 4-3 equals one V
c 3×4 = 12 V
d 3+4 = 7 V

Answer 1

c 3×4 = 12 V

The correct calculation for voltage is V = I x R, where V is the voltage, I is the current, and R is the resistance. Therefore, V = 4 A x 3 ohms = 12 V.
