The rms value of current in a 50 Hz AC source is 4 A. What will be the value of current after 1/400 seconds after its value becomes zero ?

Explanation

To solve the problem, we need to determine the value of the alternating current (AC) at a specific time after it has become zero. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the given information
The problem states that the RMS (Root Mean Square) value of the current in a 50 Hz AC source is 4 A. We need to find the current after \( \frac{1}{400} \) seconds after it has reached zero.

### Step 2: Calculate the peak current (I₀)
The relationship between the RMS value and the peak value (I₀) of the current is given by:
\[
