Introduction

Electrical circuits can be connected in different ways to serve different purposes. Two of the most common forms of connection are series circuits and parallel circuits. Both have their own features and benefits, so it is important to understand the difference between the two types of circuits in order to use them. effectively.

series circuit

A series circuit is one in which electrical devices are connected one after the other, so that current flows through each device in a sequence. The electric current is the same on all devices and the total resistance of the circuit is the sum of the resistances of each device. Yes one of the devices fails, the circuit is broken and all other devices stop working.

Series circuit characteristics:

  • The electric current is the same in all devices.
  • The total resistance of the circuit is the sum of the resistances of each device.
  • If one of the devices fails, the entire circuit is broken.
  • The total voltage or voltage of the circuit is divided between the connected devices.

Parallel circuit

In a parallel circuit, electrical devices are connected in such a way that each of them is connected directly to the power source. The current is divided into each device and flows through them independently. The sum of all the currents in the circuit is equal to the total current supplied by the power source. If one of the devices fails, the other devices will continue to function without problems.

Parallel circuit characteristics:

  • The current is divided into each device.
  • The total resistance of the circuit is less than the individual resistance of each device.
  • If one of the devices fails, the other devices will continue to function without problems.
  • The voltage on each device is equal to the total voltage supplied by the power source.

Conclusion

In summary, series circuits and parallel circuits have different features and benefits, depending on the purpose for which they are used. Series circuits are used for devices that require a constant current, while parallel circuits are used for devices that require different currents and voltages. It is important to understand the difference between the two types of circuits in order to use them correctly. effective way.
