In an electric circuit carrying current $I$, a $2\ \Omega$ resistor is replaced by an $8\ \Omega$ resistor without changing the connected (ideal) battery. Then :
- (a)current becomes $\frac{I}{4}$ and potential difference $\frac{V}{4}$
- (b)current becomes $\frac{I}{4}$ and potential difference remains $V$
- (c)current becomes $4I$ and potential difference remains $V$
- (d)current becomes $4I$ and potential difference $\frac{V}{4}$

(B)/ current becomes $\frac{1}{4}$ and potential difference remains V.
