Introduction to Electric circuit

An electric circuit is a closed path in which electrons move to produce electric currents. Indeed, all the simple modern marvels are a consequence of this scientific principle. Read on to understand more on the components, types, and other concepts related to electric circuits.

Types of electric circuit

There are two types of circuits found in homes and other common devices; namely series circuits and parallel circuits.

Series Circuits— Series circuits consists of several devices, each of them linked up one after another after another in just a single large loop. Though,different devices have different voltages across them, the same current flows through every device in the series circuit.

If any one of the devices in a series circuit is broken, the whole circuit fails. For instance, if there are three light bulbs connected in a series, in just one loop of wire connected to a battery. If one light bulb is unscrewed, the whole circuit fails.

Parallel Circuits —In parallel circuits, different devices are arranged so that a single source supplies voltage to separate loops of wire. The voltage in every device across the circuit is exactly the same, but in general different devices are going to see different currents. In this case, each device is going to work even if the other ones fail.

For instance, if two light bulbs are linked up in parallel and one is unscrewed, the other one will work. Modern Christmas tree lights are done in parallel circuits so that even if a single light burns out, the whole strand doesn’t have to be thrown out.
