Consider three identical resistors of resistance R. You are performing two experiments:
1: You connect two resistors in parallel and the third one in series to parallel combination.
2. You connect two resistors in series and the third one in parallel to series combination.
We can predict that equivalent resistance of circuit #1 is
| greater than resistance of circuit 2 |
| less than resistance of circuit 2 |
| same as resistance of circuit 2 |
| Impossible to predict anything without knowing particular value of R. |
