COMEDK · Physics · 19. Current Electricity
For the given electrical arrangement, what is the value of current \(I\) ?
- A \(6 \mathrm{~A}\)
- B \(5 \mathrm{~A}\)
- C \(7 \mathrm{~A}\)
- D \(8 \mathrm{~A}\)
Answer & Solution
Correct Answer
(D) \(8 \mathrm{~A}\)
Step-by-step Solution
Detailed explanation
Applying KCL at the bottom junction: \(4A + 1A = 5A\) flows upward. At the top junction, \(3A\) flows down and \(2A\) leaves to the right, so \(1A\) continues downward. Applying KCL at the middle junction: Currents entering: \(5A\) (from left) \(+ 5A\) (from bottom) \(+ 1A\)…
