Given below are two statements : Statement-I : The equivalent emf of two nonideal batteries connected in parallel is smaller than either of the two emfs. Statement-II : The equivalent internal resistance of two nonideal batteries connected in parallel is smaller than the internal resistance of either of the two batteries. In the light of the above statements, choose the correct answer from the options given below.

Options

  1. ABoth Statement-I and Statement-II are false
  2. BStatement-I is false but Statement-II is true
  3. CBoth Statement-I and Statement-II are true
  4. DStatement-I is true but Statement-II is false

Correct answer

B. Statement-I is false but Statement-II is true

Step-by-step solution

In parallel connections aligned & 1 r_ eq = 1 r₁ + 1 r₂ & E_ eq r_ eq = E₁ r₁ + E₂ r₂ aligned If E₁=E₂ and r₁=r₂, E_ eq =E₁=E₂ Statement 1 is false. r_ eq is less then both r₁ and r₂ Statement II is true
