Question

the network is an arrangement of nine identical resistors. the resistance of the network between points a and b is 1.5 ohm . the resistance r is​

Answer 1

Hey Dear,

◆ Answer -

For parallel network, r = 13.5 ohm

For series network, r = 0.167 ohm

● Explanation -

You didn't mention whether resistors are arranged parallel or series in the network.

If resistors are connected in series -

Req = n × r

1.5 = 9 × r

r = 0.1667 ohm

If resistors are connected in parallel -

Req = r / n

1.5 = r / 9

r = 13.5 ohm

Hope I cleared your query...
