When two 10 ohm resistors are connected in series, what is the net result?

When two resistors are connected in series, the total or net resistance can be calculated by simply adding the individual resistances together. In this case, both resistors have a resistance of 10 ohms. Therefore, when they are connected in series, the net resistance is:

10 ohms + 10 ohms = 20 ohms.

This summation occurs because the current flowing through each resistor must pass through each one sequentially, so the resistance of both adds up. In a series circuit, the overall resistance increases with each additional resistor connected in the same manner, leading to an increase of the total resistance. This principle is fundamental in understanding how resistors work in series configurations.
