$\rule{200}2$

Question - 2

Which of the following laboratory apparatus isn't used during the verification of Ohm's law.

Option [c] is correct. [Galvanometer]

$\rule{200}2$

Ohm's Law :

When current passes through wire and is directly proportional to the potential difference produced as it's both ends of the wire is known as Ohm's law.

Formula of ohm's law is :

$\huge\implies\sf I = V \times R$

$\frak{Here}\begin{cases} \sf{I \; is \: Current.} \\ \sf{V \: is \; voltage.} \\ \sf{R \; is \: resistance}\end{cases}$

$\rule{200}2$

Answer 2

Answer 1 :-

(b) Ammeter should be connected in series and voltmeter in parallel.

Answer 2 :-

(c) Galvanometer
