Write the general equation for the instantaneous e.m.f of a 50 Hz generator whose peak voltage is 250 V.

Explanation

To find the general equation for the instantaneous e.m.f of a 50 Hz generator with a peak voltage of 250 V, we can follow these steps:

### Step 1: Identify the given values
- Peak voltage (\(E_0\)) = 250 V
- Frequency (\(f\)) = 50 Hz

### Step 2: Write the formula for instantaneous e.m.f
The general equation for the instantaneous e.m.f (\(E\)) in an AC circuit is given by:
