Need to FinD:-
- How can you connect 4 resistors of 3 Ω so as to get a net resistance of 3 Ω .
For getting a net resistance of 3Ω , we will connect two 3Ω resistance in series . We will similarly connect the other two in series . Lastly we will connect the above two combinations in parallel.
Calculation of net Resistance,
- Since the two Resistances are connected in series , the net resistance will be ,
- Similarly the net resistance of the two resistors connected in series will be 6 Ω .
- Now they are connected in parallel this means to 6 ohm resistors are connected in parallel . So that the network distance will be ,
Hence we got the net resistance as 3Ω.
