alleryTwo resistors of 6 Ω and 3 Ω are connected in PARALLEL. The equivalent resistance is:
A9 Ω
B4.5 Ω
C2 Ω
D1.5 Ω
Answer & Solution
Correct answer: C. 2 Ω
1. 1/R_eq = 1/6 + 1/3 = 1/6 + 2/6 = 3/6 = 1/2.
2. R_eq = 2 Ω.
3. Note: parallel equivalent is ALWAYS smaller than the smallest individual resistor.
