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' = 2R.

Then V' = I'R'

V' = V since 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?
