A closed switch has a resistance of
Answer & Solution
Correct Answer:
Option
A
A closed switch allows current to flow freely through the circuit, meaning its resistance is zero or very close to zero.
This lack of resistance ensures that there is no significant opposition to the flow of electric current, allowing the circuit to be completed.
In contrast, an open switch would have infinite resistance, preventing any current from flowing through the circuit.

**A. Zero.**
In practical scenarios, a closed switch may have a small resistance (often negligible), but for the purposes of circuit analysis, it is typically considered to have zero resistance.
