1. The voltages at the various points are calculated as:

2. The individual voltage drops across each resistor are calculated as:

Then by using this equation we can say that the voltage dropped across any resistor in a series circuit is proportional to the magnitude of the resistor and the total voltage dropped across all the resistors must equal the voltage source as defined by Kirchhoff’s Voltage Law. So by using the Voltage Divider Equation, for any number of series resistors the voltage drop across any individual resistor can be found.
Thus far we have seen that voltage is applied to a resistor or circuit and that current flows through and around a circuit. But there is a third variable we can also apply to resistors and resistor networks. Power is a product of voltage and current and the basic unit of measurement of power is the watt.
In the next tutorial about Resistors, we will examine the power dissipated (consumed) by resistance in the form of heat and that the total power dissipated by a resistive circuit, whether it is series, parallel, or a combination of the two, we simply add the powers dissipated by each resistor.
