International General Certificate of Secondary Education (IGCSE) Physics Practice Exam

Question: 1 / 400

Which statement is false regarding series circuits?

They are simple to analyze

They allow voltage to be divided among components

They ensure consistent voltage across all components

In series circuits, the voltage supplied by the source is divided among the components according to their resistances. This division means that each component receives a portion of the total voltage, resulting in different voltage drops across each component. Therefore, it is not accurate to say that series circuits ensure a consistent voltage across all components, as the voltage will vary depending on the characteristics of each component in the circuit.

On the other hand, series circuits are indeed simple to analyze because the same current flows through all components, and the total resistance can be easily calculated by summing up the individual resistances. The characteristic of having identical current throughout the circuit is another defining feature of series circuits.
