# What Happens When You Add A Resistor To Parallel Circuit

By | March 13, 2023

Have you ever wondered what happens when you add a resistor to a parallel circuit? It's a fascinating topic that is often overlooked by those who are unfamiliar with electrical engineering. In this blog post, we'll dive into the details of what happens when a resistor is added to a parallel circuit and why it is important to understand these changes.

To start, it's important to understand that resistors are used in circuits to control the current flow. Think of a resistor as a “measure” for how much electrical current is allowed through a certain component or elements. This allows for more precise control of the current flow, which helps protect other components from being damaged by excessive current.

When a resistor is added to a parallel circuit, the overall resistance is reduced. This means that the same amount of current is allowed through the circuit but it will flow faster than before. This can be beneficial for circuits that need to run at a high speed, such as computer circuits. On the other hand, if the resistor is too powerful, the voltage across the circuit can drop significantly, which can be dangerous.

Adding a resistor to a parallel circuit also affects the impedance. Impedance is the resistance a signal experiences as it passes through a circuit. As the impedance is reduced, the signal will flow through the circuit more quickly. However, this can introduce noise and distortion, which can be undesirable depending on the application.

Finally, adding a resistor to a parallel circuit also affects the circuit's power consumption. With more current flowing through the circuit, the power consumption will increase. This means that more energy will be consumed by the device, which could lead to an increase in your electricity bill.

In conclusion, adding a resistor to a parallel circuit can have several benefits, including decreased resistance and impedance, increased current flow, and increased power consumption. These changes can have both positive and negative implications, so it's important to understand them before making changes to your circuit. With that in mind, you'll be able to make the best decisions for your particular application.
