In an RC series circuit R = 100 Ω and XC = 10 Ω. In this circuit

• the current and voltage are in phase
• the current leads the voltage by about 6°
• the current leads the voltage by about 84°
• the current lags the voltage by about 6°

Correct Answer: the current leads the voltage by about 6°

Explanation:

In RC circuit the current leads the voltage.
