Question

Three resistors 5 ohm ,10 ohm , 30 ohm are connected in parallel with 12 V battery. Calculate

a. Current through each resistor

b. Total current in the circuit

c. The total circuit resistance

​

Answer 1

Answer:

Total circuit resistance because of parallel side we add this answer hai 45ohm.please follow and brainlist

Answer 2

V=12V

R1, R2 and R3 are connected in parallel.

(a) Current through R1 = V/R1 = 12/5 = 2.4 A

Current through R2 = V/R2 = 12/10 = 1.2 A

Current through R3 = V/R2 = 12/30 = 0.4 A

(b) Total current in the circuit = 2.4 + 1.2 + 0.4 = 4 A

(c) Total resistance in the circuit=R

1/R = 1/R1+ 1/R2 + 1/R

1/R = 1/5 + 1/10 + 1/30

1/R = 10/30

R = 3 ohm
