Question

Calculate the current flowing through a wire of resistance 3 ohm connected to a battery of potential difference 15 V.

Answer 1

Answer:

5 amperes

Explanation:

according to ohm's law

V=IR

15=I(3)

I=15/3

I=5 amperes

the current flowing is 5amperes

Answer 2

Answer:

The current flowing through a wire of resistance 3 ohms connected to a battery of potential difference 15 V is  $5 A$

Explanation:

• Let V be the voltage, I be the current, and R be the resistance of the material, then according to ohm's law, voltage or the potential difference is directly proportional to the current flowing.

       That is,

        $V\propto I$

        Or

        $V = IR$     ...(1)

         So,  

         $I = \frac{V}{R}$       ...(2)

       We can solve this question by applying Ohm's law.

 

• In the question, it is given that,

       $V = 15\ V$

      $R = \ 3\Omega$

      Substitute these values into equation (1),

      $I = \frac{15}{3} = 5A$  

• So the current flowing  will be  $5\ A$
