Question

Find the current through a resister of resistance r=2ohm if voltage across the resistor is 6v

Answer 1

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

• Resistance (R) = 2Ω
• Voltage (V) = 6 volts

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

• Current

★$\color{darkblue}\underline{\underline{\sf Formula \: Used -}}$

★ $\underline{\sf Ohm's\: Law-}$

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

★$\color{darkblue}\underline{\underline{\sf Solution-}}$

$\implies{\sf V = iR }$

$\implies{\sf 6=i×2}$

$\implies{\sf i=\dfrac{6}{2}}$

$\implies{\sf i=3\:A}$

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

Current is $\color{red}{\sf 3\:A}$

Answer 2

$\mathtt{\huge{ \fbox{Solution :)}}}$

Given ,

Resistance (R) = 2 ohm

Potential difference (v) = 6 volt

We know that ,

Ohm's law states that the current flows through the conductor is directly proportional to the potential difference of the battery when the temperature and surrounding conditions are constant

$\sf \hookrightarrow V \propto I \\ \\ \sf \hookrightarrow V = IR$

The proportionality of constant R is called resistance of the conductor

Thus ,

6 = I × 2

I = 6/2

I = 3 amp

Hence , the current is 3 amp
