An alternating emf of 110 V is applied to a circuit containing a resistance R of `80Omega` and an inductor L in series. The current is found to lag behind the supply voltage by an angle `theta=tan^(-1)(3//4)`. Find the :
(i) Inductive reactance
(ii) Impedance of the circuit
(iii) Current flowing in the circuit
(iv) If the inductor has a coefficient of self inductance of 0.1 H. What is the frequency of the applied emf?

Explanation

Let's solve the problem step by step.

### Given Data:
- Alternating EMF (V) = 110 V
- Resistance (R) = 80 Ω
- Phase angle (θ) = tan^(-1)(3/4)

### Step 1: Find the Inductive Reactance (XL)
