Three resistors each of 9Ω to be connected in which way to get a resultant resistance of 6.25Ω.

Answer» TION:U can't get 6.25 but can get 6 ohms.First, connect 2 RESISTORS in series, so R=9+9=18ohms.Now, connect this R to other 9 ohm in Parallel.So, 1/(R(net))=(1/9)+(1/18)R(net)=18x9/(18+9)=18x9/27=6 ohmsSo, net RESISTANCE is 6 ohms.Thank you
