Question

States ohm's law and how can it be verifies only for experts!!​

Answer 1

$\small\red{\underline{{\boxed{\textbf{\:Answer\:with \: Explanation}}}}}$

$\rule{200}{2}$

$\red{\bold{\underline{\underline{ Ohm's \: Law \: Description \: :}}}}$

It states " physical condition remaining same, the current flowing through a conductor is directly proportional to the potential difference across its two ends "

• V ∝ I
• V = IR

where the constant of proportionality R is called the electrical resistance or resistance of the conductor.

$\rule{200}{2}$

$\red{\bold{\underline{\underline{{ Verification \: of\: Ohm's\:Law \: :}}}}}$

The Above Circuit Diagram is used to Verify Ohm's law take a few cells :-

Connect one cell across a nichrome wire AB, along with an ammeter and a voltmeter as shown in Figure .

Now, connect two cells and again note the voltage and the current.

Repeat the procedure for three cells and four cells.

Calculate the ratio for each set. You will find the ratio still nearly same in all the cases .

if a graph of current against voltage is plotted , it will turn to be straight line .

This shows that the current is directly proportional to the potential difference.
