Question

How many different resistance combinations are possible with two equal resistors taking both of them together?

Answer 1

Answer:

There is 2 combinations are possible.

Explanation:

Let assume that the equivalent resistance of the resistor "r" is R

The combination number of two equal resistors is 2.

If they are connected with series then the equivalent resistance will be r+r

which is equal to 2r.

And if they are connected with parallel connection then the quivalent resistance will be 1/R=1/r +1/r

=>R=2/r

Answer 2

Answer :

 2

Explanation :

Let the equivalent resistance of r can be ' R '

So , there are two types of combinations are possible with two equal resistors.

1 . Series Combination :

$\bold{R = r + r=2r}$

2 . Parallel Combination :

$\bold{1/R = 1/r + 1/r=2/r}$
