A half wave rectifier is used to supply 50V d.c. to a resistance load of `800Omega`. Diode has a resistance of 200Omega. Calculate maximum a.c. voltage required.

Explanation

To solve the problem of finding the maximum AC voltage required for a half-wave rectifier supplying 50V DC to an 800Ω load with a diode resistance of 200Ω, we can follow these steps:

### Step 1: Understand the relationship between DC voltage, load resistance, and current.
The output DC voltage (V_DC) can be expressed in terms of the load current (I_DC) and the load resistance (R_L):
\[ V_{DC} = I_{DC} \times R_L \]

### Step 2: Express the load current in terms of maximum AC current.
For a half-wave rectifier, the average (DC) current can be related to the maximum (AC) current (I_0) as follows:
