The current drawn from the battery by the network of resistors as shown in the figure is
- A 1 A
- B 2 A
- C 0.5 A
- D 0 A
Answer & Solution
Correct Answer
(B) 2 A
Step-by-step Solution
Detailed explanation
The given circuit is equivalent to given below, Now, \(\frac{1 \Omega}{2 \Omega}=\frac{2 \Omega}{4 \Omega}\) i.e., \(\frac{P}{Q}=\frac{R}{S}\) The given circuit is a balanced Wheatstone bridge. The resistance of \(5 \Omega\) in arm \(B D\) is ineffective. \(\therefore\) Now…
