A combination consists of three resistors in series. Four similar sets are connected in parallel. If the resistance of each resistor is `2 Omega`, find the resistance of this combination.

Text Solution

Verified by Experts

The correct Answer is:
`1.5 Omega`
Resistance of a combination of `3` resistors (each of resistors `2 Omega`) in series `= 6 Omega`
Resistance of parallel of `4` sets of such combinations in parallel `= (6 Omega)/(4) = 1.5 Omega`.
