Question

Good Morning Everyone,

Question :-
Give the experimental verification of ohm's law.​

Answer 1

$\huge{ \bold{ \green{give \: the \: experiment \: verification \: of \: ohm \: law}}}$

$\small{ \bold{ \blue{ answer}}}$

let resistance used for verification be R . make a circuit of R , voltmeter and ammeter measuring voltage and current through R rheostat ( variable resistor ) and a cell .

GOOD MORNING

HAVE A NICE DAY

Answer 2

In each case measure the potential difference and the current. ... This shows that the current is proportional to the potential difference. A circuit with Rheostat to verify Ohm's law. The experimental setup used in the laboratory makes use of a Rheostat to vary the potential difference V across a standard resistor R .

Hope it helps ♡︎
