#### Question

Keeping the potential difference constant, the resistance of a circuit is doubled. By how much does the current change?

#### Solution

We know that *V* = *IR*

If *V* is constant, resistance is doubled *R'* = 2*R*.

Then *V'* = *I'R'*

*V'* = *V* since *V *is constant`

` V=Txx2xxR`

`T=(v)/(2R)=I/2`

Thus, the current will get reduced to half.

Is there an error in this question or solution?
