How Does Voltage Change Around A Series Circuit

By | January 4, 2023



Electricity and circuits are essential components of modern life, from powering household appliances to providing the energy that powers our homes. But how does voltage change around a series circuit? This article will explain this important physics concept in an easy-to-understand way.

To understand how voltage behaves around a series circuit, it helps to first understand what a series circuit is, and why it is used. A series circuit is one in which all of the components are connected in a continuous loop, with each component sharing the same current. This means that if one component stops working, the entire circuit will go dark. This is why series circuits are typically used to power things like light fixtures or to control the speed of motors.

Now, when it comes to voltage, it is important to note that voltage is a measure of electrical pressure in a circuit. When a current passes through a resistor, for example, it creates a voltage across that resistor. In a series circuit, the voltage across each component is the same as the total voltage of the circuit. This means that, in essence, the voltage drops across each element in the circuit, until there is none left.

The total voltage drop across a series circuit can be calculated by adding up the individual voltage drops across each element. This is known as Ohm's Law, and it states that the total voltage drop across a series circuit is equal to the sum of the individual voltage drops. For example, if you have three resistors in a series circuit, each with a resistance of five ohms, then the total voltage drop across the circuit would be fifteen volts.

It is also important to remember that the voltage drop across any single element in a series circuit will always be less than the total voltage of the circuit. This is due to the fact that the voltage must split between each component, and thus each component will have a smaller voltage drop than the total voltage.

Finally, it is important to note that the voltage can also change when you add or subtract components from the circuit. When additional components are added, the voltage will increase as the components share the total voltage. Conversely, when components are removed, the voltage will decrease as each component now has more voltage to share.

In conclusion, voltage behaves differently in a series circuit versus other types of circuits. The total voltage drop across the circuit is equal to the sum of the individual voltage drops, and each component experiences a smaller voltage drop than the total voltage. Additionally, the voltage can also be affected by the addition or subtraction of components from the circuit. By understanding these concepts, it will be easier to understand how electricity works and how to best utilize it.
