Question

Two resistance of 6 ohm each are connected in parallel with third
resistance of ohm in series the equivalent resistance will be:
6 ohm
4 ohm
1.33 ohm
None​

Answer 1

Answer:

The correct answer is 9 ohm which means option D is correct :- None of the above

Explanation:

Let the three resistors of 6 ohm be A , B and C

Now first we have to find equivalent resistance between A and B which are connected in parallel.

So, 1/R = 1/6 + 1/6

1/R = 2/6

1/R = 1/3

R = 3 ohm

Now we have to find the equivalent resistance of all three resistors.

So, R = 3 + 6

R = 9 ohm
