Answer 1

Given: R2, R3, R4 are 2Ω and R1 is 4Ω. Potential difference across the battery is 12V

To find: The total resistance and current in the circuit?

Solution:

• Now we have given R2, R3, R4 are 2Ω and R1 is 4Ω.

• R2, R3, R4 are might be in series and R1 is in parallel with them.

• So first calculating series resistance, we get:

                   R2 + R3 + R4 = 2 + 2 + 2 = 6 ohm

• Now calculating parallel resistance:

                   1/6 + 1/4 = 1/R

                   1/R = 6+4/24

                   1/R = 10/24

                   R = 2.4 ohm

• Now we know that V=IR.

                   I = V/R

                   I = 12/2.4

                   I = 120/24

                   I = 5 A

Answer:

            So the total resistance is 2.4 ohm and current in circuit is 5 A.
