Question

A cell with zero internal resistance and emf of 2v is connected across 2,3 and 5ohm. The potential difference across 3ohm resistor will be

Answer 1

Answer:

0.6v

Explanation:

equivalent resistance of series commection is

2+3+5=10 ohm

Therefore,,current,,I=V/R

I=2/10=0.2A

Now potential difference in 3 ohm resistance is

V=I×R.           (Current is same in series)

V= 0.2×3= 0.6 V
