A `P-N` junction diode can withstand currents up to `10 mA`. Under forward bias, The diode has a potential drop of `0.5 V` across it which is assumed to be independent of current. The maximum voltage of the battery used to forward bias the diode when a resistance of `200 Omega` is connected in series with it is

Explanation

To solve the problem, we need to determine the maximum voltage of the battery used to forward bias the diode when a resistance of 200 ohms is connected in series with it. Here’s how we can approach the solution step by step:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Maximum current (I) = 10 mA = \(10 \times 10^{-3}\) A
- Potential drop across the diode (V_D) = 0.5 V
- Resistance (R) = 200 Ω
