How will you infer with the help of an experiment that the same current flows through every part of the circuit containing three resistances in series connected to a battery?
What happens to the resistance of a conductor when temperature is increased ?
$1\, kW h =3.6 \times 10^{6}$ joule.
On which factors does the resistlvity of conducting wire depend?
A wire is $1.0\, m$ long, $0.2\, mm$ in diameter and has a resistance of $10 \, \Omega$. Calculate the resistivity of its material.
