Options

A. Zero
B. Infinity
C. Finite
D. Negative

Answer

To solve the question regarding the resistance of an ideal diode in reverse biased condition, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Diode Functionality**: A diode allows current to flow in one direction (forward bias) and blocks current in the reverse direction (reverse bias).

2. **Identify the Reverse Bias Condition**: In reverse bias, the p-side (anode) of the diode is connected to the negative terminal of the battery, and the n-side (cathode) is connected to the positive terminal. This configuration prevents current from flowing through the diode.

3. **Consider the Ideal Diode**: An ideal diode is a theoretical concept where the diode has no resistance when forward biased and infinite resistance when reverse biased.

4. **Analyze Current Flow**: In the reverse biased condition for an ideal diode, no current flows through the diode. This means that the diode behaves like an open circuit.

5. **Relate Current and Resistance**: According to Ohm's Law, resistance (R) can be defined as R = V/I, where V is the voltage across the diode and I is the current flowing through it. Since the current (I) in reverse bias is zero, we can infer that the resistance must be infinite.

6. **Conclude the Resistance Value**: Therefore, for an ideal diode in reverse biased condition, the resistance is considered to be infinity.

### Final Answer:
The resistance of an ideal diode in reverse biased condition is **infinity**.
