Question

Find Equivalent Resistance.​

Answer 1

Answer:

27.5 ohm

Explanation:

2 , 15 ohms are parallel

so Rnet=R1R2/R1+R2

Rnet=225/30=7.5ohm

3,15 ohms are parallel

so Rnet=(1/R1+1/R2+1/R3)^(-1)

Rnet=(1/15+1/15+1/15)^(-1)

Rnet=(3/15)^(-1)

Rnet=5ohm

a 5ohm ,7.5 ohm and 15 ohm are in series

so Rnet=R1+R2+R3+......+Rn

Rnet=7.5+15+5

Rnet=27.5 ohm is the answer
