Question

The phasor diagram of current and voltage for a series A.C. circuit is shown in the figure. The circuit may contain

• A. Only a capacitor
• B. Only an inductor and a capacitor
• C. Only a resistor
• D. An inductor, a capacitor and a resistor

Answer 1

Answer: (D)

If voltage lags the current then circuit contains capacitive elements hence circuit may have RC or LCR.
