For example:Īll the data can be found by using Ohm’s Law, and to make life a little easier we can present this data in tabular form. Then the amount of current that flows through a set of resistors in series will be the same at all points in a series resistor network. Then, resistors in series have a Common Current flowing through them as the current that flows through one resistor must also flow through the others as it can only take one path. Since all the current flowing through the first resistor has no other way to go it must also pass through the second resistor and the third and so on. Resistors are said to be connected in “Series”, when they are daisy chained together in a single line. Resistors in series or complicated resistor networks can be replaced by one single equivalent resistor, R EQ or impedance, Z EQ and no matter what the combination or complexity of the resistor network is, all resistors obey the same basic rules as defined by Ohm’s Law and Kirchhoff’s Circuit Laws. Individual resistors can be connected together in either a series connection, a parallel connection or combinations of both series and parallel, to produce more complex resistor networks whose equivalent resistance is the mathematical combination of the individual resistors connected together.Ī resistor is not only a fundamental electronic component that can be used to convert a voltage to a current or a current to a voltage, but by correctly adjusting its value a different weighting can be placed onto the converted current and/or the voltage allowing it to be used in voltage reference circuits and applications.
