Question

Find the resistance of the conductor if 10^9 electrons are transferred in 2 minutes 40 seconds and the work done is transferring the electrons is 4.8 × 10^4 Joules .

Answer 1

Explanation:

here I=q/t & q=ne so q=10⁹×charge of electron

I=1/10¹²

v=W/q

so v=4.8×10⁴/q=3×10¹⁴ volt

so R =v/I =3×10²⁶ ohm
