For half wave rectifier if load resistance `R_(d)` is `2 k Omega` and P-N junction resistance `R_(L)` is `2 k Omega` determine rectification efficiency.

Explanation

To determine the rectification efficiency of a half-wave rectifier with the given load resistance \( R_d = 2 \, k\Omega \) and diode resistance \( R_L = 2 \, k\Omega \), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula for Rectification Efficiency**:
The rectification efficiency \( \eta \) of a half-wave rectifier can be calculated using the formula:
\[
\eta = \frac{0.406 \times R_d}{R_L + R_d}
