Question

A current of 0.24 A flows through a conductor when a potential difference of 24 V is applied between its two ends . What is it's restiance?

Answer 1

Given :

• A current of 0.24 A flows through a conductor when a potential difference of 24 V is applied between its two ends .

To Find :

• Resistance .

Solution :

$\longmapsto\tt{Current(I)=0.24\:A}$

$\longmapsto\tt{Potential\:Difference\:(V)=24\:V}$

Using Formula :

$\longmapsto\tt\boxed{V=IR}$

Putting Values :

$\longmapsto\tt{24=0.24\times{R}}$

$\longmapsto\tt{\dfrac{24}{0.24}=R}$

$\longmapsto\tt{\dfrac{{\cancel{24}}\times{100}}{{\cancel{24}}}=R}$

$\longmapsto\tt\bf{100\ohm=R}$

So , The Resistance is 100 Ω .

____________________

Ohm's Law :

It states that Potential Difference between any two points is directly proportional to the current and resistance .

• V = IR

Here :

• V = Potential Difference
• I = Current
• R = Resistance
