Question

how can three resistor of resistance 2 ohm 3ohm and 6 oh be connected to give a total resistance of a 4 ohM and 1 ohm

Answer 1

Answer:

Given: resistance of 2ohm,3ohm,6ohm..

To find: Req=4ohm, and Req=1ohm

Explanation:

for Req=4ohm,

we have to connect the resistance of 3ohm and 6ohm in parallel and 2ohm in series

R1=3*6/3+6= 2ohm

Req=2+2=4ohm.

for Req=1ohm

we have to connect resistance of 2,3 and 6ohm all are in parallel

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