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
  1. 2:1
  2. 1:4
  3. 4:1
  4. 1:2

Solution

Heat produced in resistor H=V2Rt 

Here, the potential is constant tor parallel combination.

Here R1=100 Ω, R2=200 Ω

H1H2=R2R1=200100=2:1
