Question

how you would connect three resistors each of resistance 6 ohm so that the combination has a resistance of

3 ohm and 4 ohm.

justify your answer.

Answer 1

Solution:

(i) Two resistors in parallel




Two 6 Ω resistors are connected in parallel. Their equivalent resistance will be

 

The third 6 Ω resistor is in series with 3 Ω. Hence, the net resistance of the circuit is 6 Ω + 3 Ω = 9 Ω.


(ii) Two resistors in series

 


Here Rs=6+6=12 Ω let third resistance R3=6 Ω

Two 6 Ω resistors are in series. Their equivalent resistance will be the su


∴ the total resistance is 4 Ω  .
