Description

Electric Current in Series Circuits

In a series circuit, the electric current is the same at all points. This is due to the lack of branching in the circuit, which allows for a uniform flow of charge.

  1. a

    State the behavior of electric current in a series circuit.

    Aim for approximately 1 distinct marking point.
