MCQ
Equivalent resistance of the circuit is?
- ✓2 W
- B4 W
- C6 W
- D8 W
✓
Answer
Correct option: A.
2 W
(a)
2 W
Explanation:
2 W and 3 W are in series. Their equivalent resistance is $R_1=5 W$.
$R_1$ is in parallel connection with 5 W . Their equivalent resistance is $R_2=2.5 W$.
$R_2$ is in series connection with 1.5 W . Their equivalent resistance is $R_3=4 W$.
$R_3$ is in parallel connection with 4 W . Their equivalent resistance is $R_4=2 W$.
Thus, the equivalent resistance is 2 W .
