1. Cross arms are installed over the transmission lines to:

- Improve visual look
- Support insulators
- Reduce radio interference
- Increase shunt capacitance

Correct answer: 2. Support insulators

2. In case of a strike, it is desirable that insulator should fail by:

- Puncture
- Flash-over
- Both of above

Correct answer: 2. Flash-over

3. The effect which is ignored in small transmission lines:

- Resistive
- Inductive
- Capacitive
- 2 & 3
- None of above

Correct answer: 3. Capacitive

4. Logic: Application of lumped constants to long transmission lines is impractical.

Solution: Line constants are considered to be uniformly distributed across long lines.

- Presented logic is wrong and the solution is not required
- Logic is correct, but the solution is also impractical
- The logic presents the problem which is solved by applying the solution
- Logic and solution don’t match the scenario

Correct answer: 3. The logic presents the problem which is solved by applying the solution
