Question

find current through 4 ohm 2 ohm and 3 ohm connected to a battery of 4 v three of them in parallel combination ​

Answer 1

Given :

• R1 = 4 Ohms

• R2 = 2 Ohms

• R3 = 3 Ohms

• Potential Difference = 4 V

____________________

To Find :

• Current in circuit when all are connected in parallel.

______________________

Solution :

⇒1/R_{eq} = 1/R1 + 1/R2 + 1/R3

⇒1/R_{eq} = 1/4 + 1/2 + 1/3

⇒1/R_{eq} = (3 + 6 + 4)/12

⇒1/R_{eq} = 13/12

⇒ R_{eq} = 12/13

_______________

⇒V = IR

⇒4 = I * 12/13

⇒I = 4 * 13/12

⇒ I = 13/3

⇒I = 4.33 A
