Question

How many different combinations are possible with three identical resistance each of the value of value 3ohm .find the equivalent resistance of each combination(dont post un usual answers​

Answer 1

Explanation:

When three are connected in parallel:

Equivalent resistance = 1/3+1/3+1/3 = 1 ohm

When three are connected in series:

Equivalent resistance = 3 + 3 + 3 = 9 ohms

When two are connected in series and the other one in parallel

resistance in series = 3 + 3 = 6

Equivalent resistance = (3*6)/(3+6) = 2 ohms

When two in parallel and the other one in series

Resistance in parallel = (3*3)/(3+3) = 3/2 ohms

Equivalent resistance = 3/2 + 3 = 9/2 ohms

So, we can get four possible values of resistance by using three resistors.

Your answer is 4.
