What is the resistance of a circuit when the current is 15 amps (A) and the voltage is 180 volts (V)?

To determine the resistance of a circuit, Ohm's Law is applied, which states that resistance (R) can be calculated using the formula R = V / I, where V is voltage and I is current. In this case, the voltage is 180 volts and the current is 15 amps.

By inserting the values into the formula, we have:

R = 180 V / 15 A

Calculating this gives:

R = 12 ohms

This indicates that the resistance of the circuit is 12 ohms. This answer is significant as it demonstrates the direct relationship between voltage, current, and resistance in electrical circuits. The correct result aligns with the principles of Ohm’s Law, showing how changes in these variables affect one another, which is foundational knowledge in understanding electrical circuits.
