An element in an electric heater is connected to a 232-volt supply and carries 19 amperes. What is the resistance?

Ohm's law relates voltage, current, and resistance through V = I × R. To find resistance, divide the voltage by the current: R = V / I. Here, R = 232 V ÷ 19 A ≈ 12.21 Ω. The closest whole-number option is 12 Ω, so the resistance is about 12 ohms.
