Question

The potential difference across a 3 Ohm resistor is is 6 v the current flowing in the resistor will be
1. 12A
2. 1A
3. 2A
4. 6A

Answer 1

we know that ,

V= I R

given

R= 3ohm

and ,V = 6 volt

then ,

$i = \frac{v}{r}$

I = 6/3

= 2 Ampere.

Answer 2

Given :

            Potential difference across resistor , V = 6V

            Resistance of resistor, R = 3 ohm

To Find:

           Current flowing through the resistor, I.

Solution :

                 To calculate I, the formula used-

                 V = I x R       ⇒ Ohm's Law

• According to Ohm's Law, The current flowing through the two points of a conducting body is directly proportional to the voltage across these points.
• This means, if the voltage is increased across the points, the current flowing through these points will also increase.
• And, resistance is the proportionality constant.

                Put the values in above formula-

                 6 = I x 3

                 I = 6/3

                 I = 2 A

Hence the current flowing in the resistor is 2 amperes ( option-3)
