A circuit has a current of 3.6 A and a resistance of 5.0 Ω.What is the voltage applied to the circuit?

Use Ohm’s law: voltage equals current multiplied by resistance, or V = IR. With a current of 3.6 A and resistance of 5.0 Ω, V = 3.6 × 5.0 = 18 V. Therefore, the applied voltage is 18 V, choice D.
