## Difference Between a Series and Parallel Circuit

Electricity flows through a circuit to produce electrical energy that powers various devices. To create a circuit, there are two primary ways: series and parallel. Both approach work towards providing a smooth flow of electric current, but they differ in their structure and the electrical output they create. Let’s explore the key differences between a series and parallel circuit.

### Series Circuit

A series circuit is created when the components in the circuit are all connected in a single, continuous loop. In a series circuit, the current flows through each component one after another, and their cumulative voltage adds up along the circuit. Therefore, the same current flows through each component, and the voltage will decrease every time it passes through one component.

One of the significant characteristics of a series circuit is that if any component fails, the entire circuit shuts down. For instance, if there are four bulbs in a series circuit, and one of the bulbs burns out, the other bulbs won’t light up. As each part depends on the others, the failure of one component disrupts the whole circuit.

### Parallel Circuit

In a parallel circuit, each component is connected separately to one another, with each receiving an equal voltage supply. Unlike in a series circuit, the current can split into different paths, and the voltage remains the same throughout the circuit. Here, each component gets its own path to the power source.

In a parallel circuit, each device operates independently of the others, and one piece’s failure doesn’t impact the others. For instance, if one bulb of four fails in a parallel circuit, the other bulbs continue to light up without any interruptions. In essence, the presence or absence of one bulb in a parallel circuit doesn’t impact the others, and the remaining devices continue to function seamlessly.

### Conclusion

In conclusion, while a series circuit has the advantage of simplicity, it is also reliant on all parts functioning correctly. By contrast, a parallel circuit provides a more reliable operation and prevents complete circuit failure in case of failures of one or more components. A series circuit works well in applications where the devices need the same performance and share the same power source, while a parallel circuit is ideal to ensure that devices work efficiently and independently of each other. It’s essential to be aware of the fundamental differences between a series and a parallel circuit before choosing one over the other.

Characteristics Series Circuit Parallel Circuit
Definition Components are arranged in a single path where the current flows Components are arranged in multiple paths where the current flows
Voltage Drop The voltage is divided equally among the components The voltage across each component is the same
Current The same current flows through each component The total current is divided among the components
Resistance The total resistance is the sum of all the components The total resistance is less than the smallest resistance in the circuit
Reliability If one component fails, the entire circuit will fail If one component fails, other components will continue to work
