Three voltmeters all having different resistance, are joined as shown. When some potential difference is applied across A and B, their readings are (V₁, V₂ ) and (V₃ ). Then (a) (V₁=V₂ ) (b) (V₁ V₂ ) (c) (V₁+V₂=V₃ ) (d) (V₁+V₂>V₃ )

Options

  1. Aonly a is correct
  2. Bonly b is correct
  3. Conly c is correct
  4. Donly b & c are correct

Correct answer

D. only b & c are correct

Step-by-step solution

( V ₁ ) and ( V ₂ ) are in series ( aligned & V R & V₁ V₂ ( as R₁ R₂ ) & V₁+V₂=V₃ (as V is same in parallel ) aligned )
