Question

to show an activity of ohm's law

Answer 1

V=iR when temperature and other physical conditions are constant the potential drop across a conductor is directly proportional to the current flowing through it.

Answer 2

Ohm's law states that potential difference across a conductor is directly proportional to the current flowing through it at a given temperature..
V = IR
We have to take an ammeter ,voltmeter registor,battery and a plug key.
We will pass the current through the circuit.
We have to change the current and the potential difference time to time and record the resistance.
To change the potential difference we have to change the number of cells.
We will make a table recording the current, potential difference and resistance.
We will make observations that resistance is constant at every situation.
Hence resistance is constant and it proves the Ohm's law.


NOTE:The experiment should be conducted at a constant temperature.
