Two resistors of resistance, 100   Ω and 200   Ω are connected in parallel in an electrical circuit. The ratio of the thermal energy developed in 100   Ω to that in 200   Ω in a given time is

Options

  1. A2 : 1
  2. B1 : 4
  3. C4 : 1
  4. D1 : 2

Correct answer

A. 2 : 1

Step-by-step solution

Heat produced in resistor H = V 2 R t Here, the potential is constant tor parallel combination. Here R 1 = 100   Ω , R 2 = 200   Ω H 1 H 2 = R 2 R 1 = 200 100 = 2 : 1
