A $100\ \Omega$ resistor and a capacitor of reactance $100\ \Omega$ are in series across an ac supply. The phase angle between the current and the supply voltage is
Answer: (B) $45°$, current leading
$\tan\phi = \dfrac{X_C}{R} = 1 \Rightarrow \phi = 45°$. In an RC circuit the current leads the voltage.
