A current of 0.1 A flows through a 25 ~ resistor represented by the circuit diagram. The current in the 80 ~ resistor is

Options

  1. A0.1 ~A
  2. B0.2 ~A
  3. C0.3 ~A
  4. D0.4 ~A

Correct answer

C. 0.3 ~A

Step-by-step solution

0.1 (25+ 20 60 20+60 )=i₂ 20I₂=0.2 ~A Hence, i through 80 0.1+0.2=0.3 ~A
