Question

Calculate the resistance of a conductor if the current through it is 0.15 A and the
potential difference across it is 1.5V

Answer 1

$\LARGE{ \underline{\underline{ \orange{ \sf{Required \: answer:}}}}}$

GiveN:

• Current passing = 0.15 A
• Potential difference = 1.5 V

To FinD:

• The Resistance of the conductor?

Step-wise-Step Explanation:

We have current and potential difference. We need to find the resistance which can be done by using ohm's law:

$\large{ \because{ \boxed{ \rm{V = IR}}}}$

Where,

V is the potential difference

I is the current flowing

R is the resistance of the conductor.

Plugging the values,

⇒ V = IR

⇒ 1.5 V = 0.15 A × R

⇒ R = 1.5 / 0.15 V/A

The unit V/A can now be written as Ohms ($\rm{\Omega}$). It is the SI unit of Resistance.

⇒ R = 10 $\rm{\Omega}$

Hence, the resistance of the conductor is 10 Ohms.
