5 cells, each of emf 0.2V and internal resistance `1 Omega` are connected to an external circuit of resistance of `10 Omega`. Find the current through external circuit-

A

`1/2.5 A`

B

`1/10 A`

C

`1/15 A`

D

`1/2 A`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_(eq) = 5 xx 0.2 = 1V`
`r_(eq) = 5 Omega`
`I = 1/(5 + 10) =1/15 A`
