Question

show the combination of 3 resistors each of 6ohm value such that effective resistance of combination should be 4 ohms​

Answer 1

Explanation:

If you put 2 resistors in series and one resistor parallel to both of them then you will get total resistance as 4 ohms

In series=6+6=12 ohms

Total resistance=1/12+1/6

=1+2/12

=3/12

Effective Resistance =12/3 =4ohms
