The battery in the diagram is to be charged by the generator `G`. The generator has a terminal voltage of `120` volts when the charging current is `10` amperes. The battery has an emf of `100` volts and an internal resistance of `1` ohm. In order to charge the battery at `10` amperes charging current, the resistance `R` should be set at

A

`0.1 Omega`

B

`0.5 Omega`

C

`1.0 Omega`

D

`5.0 Omega`

Text Solution

Verified by Experts

The correct Answer is:
C

Applying loop law
`120-10R-10xx1-100=0 implies R=1 Omega`
