A coil of negligible resistance is connected inseries with `90 Omega` resistor acorss a 120 V -60 Hz line. A voltmeter reads 36 V across the resistance. Find voltage across the coil and inductance of the coil.

Explanation

To solve the problem step-by-step, we will follow these calculations:

### Step 1: Calculate the current (I) through the circuit
Given that the voltage across the resistor (V_R) is 36 V and the resistance (R) is 90 Ω, we can use Ohm's Law to find the current (I).

\[ I = \frac{V_R}{R} = \frac{36 \, \text{V}}{90 \, \Omega} = 0.4 \, \text{A} \]
