A closed switch has a resistance of
A. Zero
B. About 50 ohms
C. About 500 ohms
D. Infinity
Answer: Option A
Solution(By Examveda Team)
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.
This Question Belongs to Electrical Engineering >> Current Electricity
A closed switch ideally has very low resistance, approaching zero ohms, because it allows current to flow freely through the circuit.
### Therefore, the correct answer is:
**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.
