# How To Find Total Resistance In Series Parallel Circuits

Trying to figure out how to calculate total resistance in series parallel circuits can seem difficult, but with the right information and knowledge you can easily figure out the total resistance of this type of circuit. Resistors are one of the most important components in electronic circuits. They are used to control current flow, create voltage drops and regulate the power levels in a circuit. When two or more resistors are connected in series or parallel, their combined effect is known as the total resistance. This article will discuss the different methods for finding the total resistance in series parallel circuits.

## Understanding Series Parallel Circuits

The first step in determining the total resistance of a circuit with resistances connected in series or parallel is to understand what makes a series parallel circuit. A series parallel circuit is when you have two or more resistors connected in both series and parallel. The number of resistors in series or parallel will determine the total resistance of the circuit. When calculating the total resistance, one must analyze each branch in the circuit separately to determine the individual resistances before adding them all together.

## Resistance Value for Each Resistor

Before calculating the total resistance of a series parallel circuit, you must first establish the resistance value for each resistor. Resistors are electronic components that are used to control the voltage or current in a circuit. Resistors come in various forms, including fixed, variable, and adjustable resistors. Fixed resistors are devices that have a fixed resistance value, and they do not change with the operation of the circuit. Variable resistors, on the other hand, change resistance depending on the situation in a circuit, and adjustable resistors can also be adjusted manually to suit certain requirements.

## Calculating Total Resistance of Series Parallelcircuit

Once you have determined the resistance value for each resistor, you can begin to calculate the total resistance of the series parallel circuit. The total resistance of a series parallel circuit can be calculated by the following formula: Rt=R1+R2+R3+R4… Where Rt is the total resistance, R1 is the resistance of the first resistor, and R2 is the resistance of the second resistor, and so on. All of the resistors in the circuit are added together to find the total resistance.

## Calculating Total Resistance of Series Circuit

If the circuit contains only resistors connected in series, then the total resistance can be found by simply adding all of the individual resistances together. This can be done by using the same formula above but replacing R1, R2, R3, etc. with the individual resistances of each resistor. For example, if you have a circuit with four resistors connected in series, the total resistance can be obtained by adding the resistance of each resistor: Rt=R1+R2+R3+R4.

## Calculating Total Resistance of Parallel Circuit

Calculating the total resistance of a circuit with resistors connected in parallel is slightly more complicated than calculating the resistance of a series circuit. To obtain the total resistance of a parallel circuit, one must first figure out the total current flowing through the circuit. This can be done by dividing the total voltage of the circuit by the resistance of each resistor. Then, the total resistance is determined by dividing the total voltage of the circuit by the total current.

## Conclusion

Finding the total resistance in series parallel circuits can be a daunting task at first, but with the right information, it can be easily accomplished. By understanding the basics of series parallel circuits, establishing the resistance values for each resistor, and using the appropriate formulas, you can quickly calculate the total resistance of this type of circuit.
