`6Omega` and `12Omega` resistors are connected in parallel . This combination is connected in seires with a 10 V batery and `6Omega` resister . What is the potential difference between the teriminal of the `12Omega` resistor ?

A

4V

B

16V

C

2V

D

8V

Text Solution

Verified by Experts

The correct Answer is:
A

Sensitivity of galvanometer , `(i_g)/(i) = (S)/(G+S)`
`(10)/(60)= (s)/(G+S)`
G+5S
Galvanometer resistance , `G=20 Omega`
Rightarrow `S= (20)/(5)`
therefore `S= 4Omega`
