Question

If potential difference is 3V and current flowing through the conductor is 600mA . Find the resistance of the conductor

Answer 1

Answer:

V=3V

I=600mA=0.6A

R=V/I

=3/0.6

=5 ohm

Ans》5 ohm

Answer 2

$\color{darkblue}\underline{\underline{\sf Given-}}$

• Potential Difference (V) = 3Volt
• Current flowing through conductor = 600mA

$\underline{\sf Convert \: milliamphere\; to amphere-}$

We know that -

$\color{green}\implies{\sf 1A = 10^{-3}mA}$

$\implies{\sf i = 600mA}$

$\implies{\sf i = 600 ×10^{-3}A }$

$\color{darkblue}\underline{\underline{\sf To \: Find-}}$

• Resistance of conductor (R).

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

❏ Ohm's Law

$\color{violet}\blacksquare\underline{\boxed{\sf V=iR}}$

$\implies{\sf 3=600×10^{-3}×R }$

$\implies{\sf 3=6×10^{2-3}×R}$

$\implies{\sf 3=6×10^{-1}×R}$

$\implies{\sf R=\dfrac{3}{0.6}}$

$\color{red}\implies{\sf R=5Ω }$

$\color{darkblue}\underline{\underline{\sf Answer-}}$

Resistance of conductor is $\color{red}{\sf 5Ω}$.
