A 80 V - 800 W heater is to be operated on a 100 V - 50 Hz a.c. supply. Calculate the inductance of the choke required.

Explanation

To solve the problem of calculating the inductance of the choke required for an 80 V - 800 W heater to operate on a 100 V - 50 Hz AC supply, we can follow these steps:

### Step 1: Calculate the Current Required by the Heater
The power (P) consumed by the heater is given as 800 W, and the voltage (V) is 80 V. We can use the formula for power:

\[ P = V \times I \]
