Consider the following statements A and B and identify the correct answer:

A. For a solar-cell, the I-V characteristics lies in the IV quadrant of the given graph.
B. In a reverse biased pn junction diode, the current measured in (µA), is due to majority charge carriers.

Question

When a potential difference V is applied across a wire of resistance R, it dissipates energy at a rate W. If the wire is cut into two halves and these halves are connected mutually parallel across the same supply, the same supply, the energy dissipation rate will become:

Answer 1

Step 1: Evaluate Statement A

The I − V characteristics of a solar cell reside in the fourth quadrant because the cell converts light energy to electrical energy, thereby producing current. This confirms Statement A is correct.

Step 2: Evaluate Statement B

In a reverse-biased pn-junction diode, current flow (leakage current) is attributed to minority carriers, not majority carriers. Therefore, Statement B is incorrect.

Step 3: Final Verdict

Statement A is correct, while Statement B is incorrect.
