Question

3 resistors of resistance 4ohm, 6ohm, 12 ohm are combined in parallel, what is the equivalent resistance of the combination ​

Answer 1

Answer:

You can use the formula of parallel combination

given as: 1/R = 1/R1 + 1/R3.....

Therefore...

1/R= 1/4+1/6+1/7

1/R=1/2

So, equivalent resistance is 2 ohm..
