Answer 2

__________________________________________________________

Ohm's law used to defined the relation between potential difference , current and resistance in a conductor

i.e. V=IR

We can verify it by the following activity....

Material required :

@A resistor of about 5 Ω

@An ammeter

@A Voltmeter
