Question

Three resistances of 2, 3 and 5 W are connected in parallel to a 10 V battery of negligible

internal resistance. The potential difference across the 3 W resistance will be_______.

(a) 2 V (b) 3 V

(c) 5 V (d) 10 V​

Answer 1

Answer:

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

ANSWER

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 3Ω resistor is equal to potential difference of cell =10V

Answer-(D)

Answer 2

Answer:

your answer is d option 10v
