Quizplus · Accepted Answer

In a series RLC circuit, the current is the same at all points in the circuit, making statement i true. The voltage drop across the resistor is indeed in phase with the current, making statement ii true. The voltage drop across the capacitor lags the current by 90 degrees, confirming statement iii as true. Lastly, the voltage drop across the inductor leads the current by 90 degrees, making statement iv true as well. Therefore, all statements are correct.
