Question

Three resistances of 2, 3 and 5 $\Omega$ are connected in parallel to a lay battery 10V with negligible internal resistance. The potential difference across the $3\Omega$ resistance will be

• A. 2 V
• B. 3 V
• C. 5 V
• D. 10 V

Answer 1

The correct option is D 10 V

Emf of cell$=E=10V$

In parallel combination of resistors, the potential difference across each resistor is same and is equal to the potential difference between the point between which resistors are attached.

Here potential difference across $3\Omega$ resistor is equal to potential difference of cell $=10V$

Answer-(D)
