Question

If the resistance in a 120-V electrical circuit were 30 ohms, what would the current be in amperes?

a) 4 A
b) 3 A
c) 2 A
d) 1 A

Answer 1

The current in the circuit would be 4 A. the current in the circuit, we can use Ohm's Law which states that V = IR, where V is the voltage, I is the current, and R is the resistance. In this case, the resistance is given as 30 ohms and the voltage is 120 V. Rearranging the formula, we get I = V/R = 120/30 = 4 A.

Step-by-step explanation:

To calculate the current in the circuit, we can use Ohm's Law which states that V = IR, where V is the voltage, I is the current, and R is the resistance. In this case, the resistance is given as 30 ohms and the voltage is 120 V. Rearranging the formula, we get I = V/R = 120/30 = 4 A. Therefore, the current in the circuit would be 4 A.
