Question

0.5 ampere current flows through a conductor when 2volt potential difference is applied to its end . Find the resistance of the conductor

Answer 1

Answer:

The correct answer of this question is 4 ohm = R

Explanation:

Given - 0.5 ampere current flows through a conductor when 2volt potential.

To Find -  Find the resistance of the conductor .

The ratio of the potential difference across a conductor's end to the current flowing through it is the conductor's resistance. The ohm () is its SI unit.

$I$ = $0.5$A

$v$ = $2v$  and $R = ?$

$v = RI$

$2$ = $0.5$ × $R$

$2/0.5$ = $R$

$4 ohm = R$

So, the resistance of the conductor is $4 ohm = R$

Answer 2

As per the data given in the above question,

It is given that the current is $0.5\:A$.

The potential difference between two point is $2\:V$.

We have to find the resistance of the conductor.

Here we have to use the formula of ohm's law,

i.e. $V=IR$

Where v is voltage,

I is current,

and R is resistance.

Substitute the value in ohm's law we get,

$R=\frac{V}{I} \\R=\frac{2}{05} \\R=4\: ohm$

Hence the resistance of the conductor is $4$Ω.
