Question

Statement 1: The flow of current in a poor conductor is impossible.

Statement 2: Under certain conditions current flows through a poor conductor.

• A. Both statements are true and statement 2 is the correct explanation of statement 1.
• B. Both statements are true and statement 2 is not the correct explanation of statement 1.
• C. Statement 1 is true and Statement 2 is false
• D. Statement 1 is false and Statement 2 is true

Answer 1

The correct option is D

Statement 1 is false and Statement 2 is true

Explanation for the correct option

1. A conductor or electrical conductor is a substance or material that allows electricity to flow through it.
2. The conductors which do not allow electricity to flow through them easily under normal conditions are referred to as poor conductors.
3. Poor conductors do not allow electricity to flow through them easily, but under certain conditions, we can make current flow through them. This contradicts statement 1 and supports statement 2.
4. For example: Air being a mixture of neutral or inert gases contains few or no charged particles for conduction of electricity, so acts as a poor conductor of electricity but current flows through the air during lightning when the potential difference between Earth and cloud becomes very high.

Thus Statement 1 is false and Statement 2 is true

Hence the correct option is option(D) i.e. Statement 1 is false and Statement 2 is true
