Resistors in series and parallel; power

Explanation of question 4

Two resistors, each of value 120, are connected in parallel across a 12V supply. The current in each resistor will be

  1. 0.05A
  2. 0.1 A
  3. 0.15A
  4. 0.2 A

The answer is :- 2

P.D. across each resistor = 12 V, and resistance of each resistor is 120 ,

therefore, current in each resistor = 12/120 = 0.1 A.
