series circuit
Definition
A series circuit is a type of electrical circuit where the components are connected end-to-end. This means that the current flows through all of the components in the circuit in the same way.
The voltage across each component in a series circuit is the same, but the current through each component can be different. The total resistance of a series circuit is equal to the sum of the resistances of the individual components.
Series circuits are often used in simple electrical devices such as flashlights and doorbells. They are also used in more complex devices such as computers and radios.
How can the word be used?
The components in a series circuit are connected end to end.
Different forms of the word
Noun:
- an electric circuit in which the components are connected end to end, so that the current flows through all of them in the same direction.
Etymology
The word "series circuit" is a compound word, consisting of the words "series" and "circuit".
The word "series" comes from the Latin word "series", which means "row" or "sequence".
The word "circuit" comes from the Latin word "circuitus", which means "going around".
The first recorded use of the word "series circuit" in English was in the 19th century.
The word "series circuit" is an English word, and it is not related to any other languages.

What is a series circuit?
AQA Science Exam Question and Answer
Question:
Explain the concept of a series circuit in electricity, including the arrangement of components and the characteristics of current flow, voltage, and resistance.
Answer:
A series circuit is an electrical circuit configuration where components, such as resistors or bulbs, are connected end-to-end in a single pathway. In a series circuit, the same current flows through all components because there is only one path for the electric current to follow. This characteristic ensures that the current remains constant throughout the circuit.
The voltage, however, is divided among the components in a series circuit. Each component receives a portion of the total voltage, which means that the sum of the individual voltage drops across the components is equal to the total applied voltage. This voltage division is a key feature of series circuits.
In terms of resistance, the total resistance in a series circuit is the sum of the resistances of all components. As more resistors are added in series, the overall resistance increases, resulting in a decrease in current flow according to Ohm's law (I = V/R).
Series circuits have practical applications, such as in decorative lighting where bulbs are connected in series to create a sequential lighting effect. However, the disadvantage of series circuits is that if one component fails or is removed, the entire circuit is interrupted, and all components may stop functioning.
In conclusion, a series circuit consists of components connected sequentially, sharing the same current while dividing the voltage across them. The total resistance in a series circuit is the sum of individual resistances, and while series circuits have specific applications, they also come with limitations related to component failure.
