Question

find the resistance value​

Answer 1

Answer:

resistance in parallel

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

1/R eff = 1/20000 + 1/ 100000 + 1/25000

1/R eff = 5+1+4 / 100000

1/R eff = 10/100000

R eff = 10000 = 10 k ohm

in parallel potential difference is constant

for total current

V=I*R eff

I = V/ Reff

I = 100/10000

I = 0.01 A

for current through R1

V = I1 * R1

I1 = V/R1

I1 = 100/ 20000

I1 = 0.005 A    

I1= $5*10^{-3}$ A

for current through R2

V=I2*R2

I2=V/R2

I2= 100/100000

I2=0.0001 A

I2= $10^{-4}$ A

For current through R3

V=I3*R3

I 3=V/R3

I 3=100/25000

I 3 = 0.004 A

I 3 = $4*10^{-3}$ A
