The bulb which glows with maximum intensity in the given circuit is

Options

  1. A4 bulb
  2. B2 bulb
  3. C3 bulb
  4. D6 bulb

Correct answer

A. 4 bulb

Step-by-step solution

Given circuit is As, resistance of portion B is higher. A greater potential drop across B occurs. Now, in section B , Power, P= V^2 R So, least resistance gives a higher power output. 4 bulb glows with maximum intensity.
