The figure shows currents in a part of electric circuit. Then current I is

Options

  1. A3.5 A
  2. B4 A
  3. C1.5 A
  4. D2.5 A

Correct answer

A. 3.5 A

Step-by-step solution

According to Kirchhoff's first law, At junction A , I _ A =1+4=5 ~A At junction B , I _ A = I _ BC +0.5 I _ BC =4.5 ~A At junction C , I = I _ BC -1=4.5-1=3.5 ~A
