C)
D)
Correct Answer: C
Solution :
[c] The current through the resistance R \[I=\left( \frac{\varepsilon }{R+r} \right)\] The potential difference across R, \[V=IR=\left( \frac{\varepsilon }{R+r} \right)R\] Thus V increases as R increases up to certain limit, but it does not increase further.You need to login to perform this action.
