The current flowing in a series circuit is the same everywhere. Figure caption, A series circuit with two bulbs and one cell. The ammeter will read the same at points 1, 2 or 3. In series circuits ...

Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits. We can calculate the voltage, current and resistance in these circuits.

The functions of basic electronic components are revealed through a series of experiments as students figure out how to create circuits that light up LEDS, sound buzzers, use resistors to dim lights, ...
