Ratio of thermal energy released in two resistor R and 3 R connected in parallel in an electric circuit is :

Options

  1. A3 : 1
  2. B1 : 1
  3. C1 : 3
  4. D1 : 27

Correct answer

A. 3 : 1

Step-by-step solution

Thermal energy is given by H = P t = V ^2 R t Here, voltage V is same. H ₁ H ₂ = V ^2 t R V ^2 t 3 R =3: 1
