Question

ohm's law and heating effect of class 10th​

Answer 1

Answer:

ohm's law -

ohm's law states that the potential difference across the two ends of the conductor is directly proportional to the current flowing through the conductor, provided that the temperature remains constant.

by ohm's law,

V ∝ I

to remove proportionality sign, we substitute a constant R i.e. resistance

∴ V = IR

heating effect of current :-

when certain amount of electric current passes through a conductor, certain amount of heat is produced in the conductor which can be used for various purposes.

the amount of heat produced due to electric current can be given by joule's law of heating.
