Question

When the potential difference across a wire is doubled, how will the following quantities be affected (i) resistance of the wire (ii) current flowing through the wire?

Answer 1

Answer:

¡) V=IR

R=V/I(FORMULA)

R=2V/I

R=2R (V/I replaced byR)

¡¡) I=2V/R

I=2I(Similarly V/R replaced by I)
