Question

Effective resistance of a circuit connected in parallel of resistors 5ohm 25 ohm 100ohm and find current of the circuit

Answer 1

Step-by-step explanation:

resistance in parallel

1/R = 1/R1 + 1/R2 + 1/R3

1/R = 1/5 + 1/25 + 1/100 ( taking l.c.m)

1/R = 20 + 4 + 1 /100

1/R = 25/100

1/R = 1/4

so R is 4 ohm

current = voltage/4 ohm
