# You are given three resistors each of 3Ω and you are asked to get all possible values of resistance when you connect them in different combinations. How many values of resistance can you get?

Here: R1 = 3Ω

R2 = 3Ω

R3 = 3Ω

Parallel combination:

R1, R2 and R3 connected in stair like pattern one above the other.

Series Combination:

R1, R2 and R3 connected in same line across the potential difference V

Mixed combination:

R1 is connected in series with the parallel combination fo R2 and R3.

Putting the values of the resistance, we get

Thus, we get

Rs= R1+ Rp= 3+1.5= 4.5 Ω

Thus, the net resistance of the circuit is 4.5
