Current Electricity

A 3 volt battery with negligible internal resistance is connected in a circuit as shown in the figure. The current I, in the circuit will be

  1. 1.5 A
  2. 1 A
  3. 2 A
  4. 1/3 A

Answer

Two 3 Ω resistors are in series with one 3 Ω resistor.

Equivalent Resistance = (3+3) x 3 / (3+3) + 3 = 18/9 = 2 Ω

Current, I = V/R = 3/2 = 1.5 A

The correct option is A.
