COMEDK · Physics · 19. Current Electricity
A current of 3A enters one vertex P of an equilateral triangle PQR having three resistors of \(1\Omega\) each forming the sides of the equilateral triangle as shown. The value of \(i_2\) in amperes is:
- A \(1\text{A}\)
- B \(1.5\text{A}\)
- C \(2\text{A}\)
- D \(1.7\text{A}\)
Answer & Solution
Correct Answer
(A) \(1\text{A}\)
Step-by-step Solution
Detailed explanation
The current of \(3\text{A}\) enters at node P and leaves at node R. The circuit consists of two parallel paths between P and R. The first path is the direct branch PR with resistance \(R_1 = 1\Omega\). The second path is the branch PQR, which has two \(1\Omega\) resistors in…
