How much current is drawn by the primary of a transformer connected to `220V` supply when it delivers power to a `110V-550W` refrigerator ?

Explanation

To determine the current drawn by the primary of a transformer connected to a 220V supply when it delivers power to a 110V-550W refrigerator, we can follow these steps:

### Step 1: Identify the given values
- Voltage across the primary (Vp) = 220V
- Power delivered to the refrigerator (P) = 550W
- Voltage across the secondary (Vs) = 110V

### Step 2: Calculate the current in the secondary (Is)
