**Q.**The electric field due to a dipole at a distance r on its axis is

**Q.**

The correct relation between heat produced (H) and electric current (I) flowing is:

**Q.**

V=IR, from this equation it's clear that V is directly proportional to I and R..

I=V/R, from this equation it's clear that I is directly proportional to V and inversely proportional to R.

But when V is directly proportional to R and I is directly proportional to V then why is I not directly proportional to R?
