An alternating emf of frequency 50 Hz is applied to a circuit with a resistor of 200 an inductor of 100 mH and a capacitor of 30 uF connected in series.
(i) What is the angle by which the current leads or lags the applied emf ?
(ii) Represent the voltage and the current in a vector diagram showing the phase angle.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the Inductive Reactance (XL)
The inductive reactance \(X_L\) is given by the formula:
\[ X_L = \omega L \]
where \(\omega = 2\pi f\) and \(L\) is the inductance.
