Question

Calculate the current when resistance is 4 ohm and potential difference is 2

Answer 1

$<b ><u >$ We are given,

Potential difference, V = 2 V

Resistance, R = 4 ohm

Current, I =?

We know that, V = IR

So, I = V/ R = 2/ 4 = 1/ 2 = 0.5 A

Hence, the answer is 0.5 A

Answer 2

⇒ Resistance = R = 4Ω

⇒ Potential Difference = V = 2V

⇒ Formulas which will be used here ;

    1. V $\bold{\propto}$ I

    or V = IR (Ohm's Law, Where R is constant called Resistance.)

⇒ Given ;

    1. R = 4Ω

    V = 2V

⇒ Finding value of I ;

    From formula, we have I = $\bold{\frac{V}{R}}$

    Therefore, I =  $\bold{\frac{2}{4}}$

     ⇒ I =  $\bold{\frac{1}{2}}$

     ⇒ I =  0.5 A

⇒ Precautions to be taken ;

    1. I is to be always written in A (Ampere.)

    2. R is to be always written in Ω(Ohm or Omega.)

    3. Potential Difference is to be always written in V.
