A transformer is used to step down mains supply of 220 V to 22 V. Its primary draws a current of 6 A and secondary draws a current of 50 A . Calculate the efficiency of the transformer .

Explanation

To calculate the efficiency of the transformer, we can follow these steps:

### Step 1: Identify the given values
- Primary voltage (V1) = 220 V
- Secondary voltage (V2) = 22 V
- Primary current (I1) = 6 A
- Secondary current (I2) = 50 A
