Two resistors are said to be in series when same current flows through them. A series circuit is a circuit in which resistors are arranged in a chain so the current has only one path to take.

When are resistors in seriesresistors are in series whenever the flow of charge called the current must flow through devices sequentiallyfor example if current flows through a person holding a screwdriver and into the earth then in a could be the resistance of the screwdrivers shaft the resistance of its handle the persons body resistance and the.
Current in resistors in series. Resistors in series and parallel example no2 find the equivalent resistance r eq for the following resistor combination circuit. In a parallel circuit the voltage across each of the components is the same and the total current is the sum of the currents flowing through each component. The total resistance of the circuit is found by simply adding up the resistance values of the individual resistors.
In the following example the resistors r 1 r 2 and r 3 are all connected together in series between points a and b with a common current i flowing through them. Individual resistors can be connected together in a series connection a parallel connection or combinations of both series and parallel together. In the following resistors in parallel circuit the resistors r 1 r 2 and r 3 are all connected together in parallel between the two points a and b as shown.
Series and parallel circuits. Resistors in series can be replaced by a single resistor. The current is the same through each resistor.
This results in a more complex circuit whose total circuit resistance is a combination of the individual resistors. In a series circuit the current that flows through each of the components is the same and the voltage across the circuit is the sum of the individual voltage drops across each component. 7 10 00 section 191 series circuits.
In many electrical circuits resistors are connected in series or parallela designer might for example combine several resistors with standard values to reach a specific resistance valuefor series connection the current through each resistor is equal. How to calculate the equivalent resistance value for resistors in series. All the resistors follow the basic laws like ohms law and kirchhoffs current law irrespective of their combination and complexity.
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. Parallel resistor circuit in the previous series resistor network we saw that the total resistance r t of the circuit was equal to the sum of all the individual resistors added together. Again at first glance this resistor ladder network may seem a complicated task but as before it is just a combination of series and parallel resistors connected together.
