Question

three resistance 2, 3,5 ohms are connected in parallel to a10 volts battery. of negligible. internal resistance. then the potential difference across the 3 ohm resistance

Answer 1

Current flowing through conductor=I
E=10V
Total resistance=10 ohm
Relationship using ohms law=
I=E/R
I=10/10
I=1A
Potential drop across 3 ohm resistor =
V,Potential difference=1×3=3V

Answer 2

Given that,

Three resistance 2,3,5 ohms are connected in parallel to a 10 volts battery of negligible internal resistance.

To find,

The potential difference across the 3 ohm resistance.

Solution,

We know that, for a parallel combination of resistors the current across each resistors divides while the potential difference throughout each resistor is same.

It means that the potential difference across the 3 ohm resistance is same as voltage of battery i.e. 10 volts.
