Question

how can three resistors of resistance 2ohm ,3ohm and 6ohm are connected to give a total resistance of

Answer 1

Answer:

For 4 ohm:

We should connect 3ohm and 6ohm in parallel with 2ohm in series.

1/Rp=1/R1+1/R2

1/Rp=1/3+1/6

1/Rp=2/6+1/6

1/Rp=3/6

1/Rp=1/2

Rp=2

•°•Req=2+2=4ohm

For 1 ohm:

We should connect all the resistance in parallel combination.

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

Req=1/2+1/3+1/6

Req=3/6+2/6+1/6

Req=6/6

Req=1
