# All you should know about Series and Parallel Circuits

## Series and Parallel Circuits

Simple circuits (those with only a few components) are typically quite easy to grasp for novices. When more components join the party, though, things may get sticky. What is the direction of the current? What’s going on with the voltage? Is it possible to make this more understandable? Intrepid reader, have no fear. There’s a lot of useful information after that.

### What is the definition of a series circuit?

When the flow of current is the same through all of the circuit’s components, it’s called a series circuit. The current in a series circuit has only one route.

The current and voltage relationships in a series circuit are the inverse of those in a parallel circuit. The voltage across each series element (V1, V2, V3), on the other hand, fluctuates depending on the impedance (in this case, the resistance) of each element. The voltage provided by the source (Vs) is equal to the total of the individual voltage drops across each series element, according to Kirchhoff’s Voltage Law (KVL).

### The benefit of series circuits

• It features a straightforward style that is simple to comprehend.
• It does not easily overheat.
• It has a larger output voltage, allowing us to connect more powerful appliances to it.
• Throughout the circuit, it maintains the same current.

Circuit resistance increases as the total number of components in the circuit grow.

If a single point in the circuit fails, the entire circuit will fail.

### What is the definition of a parallel circuit?

A parallel circuit is one in which the current flows across two or more pathways. All of the components in a parallel circuit have the same voltage.

The voltage across each element in a parallel circuit is the same and equal to the source voltage (Vs), and the current through each element (I1, I2, I3) varies depending on the impedance (in this case, resistance) of each element. The overall current coming from the source (Is) is equal to the sum of the individual currents flowing through each parallel element, according to Kirchhoff’s Current Law (KCL).

In a parallel circuit, if one component fails, the current continues to flow through the other components, allowing the remaining components to function properly.

Because the voltage across each component in a parallel circuit is the same, all components function efficiently.

You may quickly connect or detach a new component in a parallel circuit without impacting the operation of another component.
