Question

Judge the equivalent resistance when the following are the in parallel :

1 ohm , 10^3 ohm, 10^6 ohm

Answer 1

hey

1/Req = 1/R1 + 1/R2 + 1/R3

Here R1 = 1 R2 = 1000 R3 = 1000000

1/Req = 1/1 + 1/1000 + 1/1000000

1/Req = 1000000 + 1000 + 1 / 1000000

1/ Req = 1001001/1000000

Req = 1000000/1001001
