Find the equivalent resistance of the network in fig. between points A and C.

Text Solution

Verified by Experts

The resistance `R_1 ` is connected in series with resistor of `7.5 Omega`, hence the equivalent resistance between points A and C is ,
`R_2 = (R_1 + 7.5) ` ohm = `(7.5+7.5)` ohm = `15 Omega`
