Q-00004507
If a wire's resistance is 10 Ω, what would be the total resistance in a parallel circuit with another wire of resistance 10 Ω?
1
5 Ω
2
20 Ω
3
100 Ω
4
10 Ω
Answer and Solution
Answer
A. 5 Ω
Solution:
The total resistance R_p in parallel is given by 1/R_p = 1/R_1 + 1/R_2. Therefore, R_p = 10 Ω || 10 Ω = 5 Ω.
