Electric circuits – WJECElectrical component symbols
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.
Electrical circuits can be represented by circuit diagrams. The various electrical componentA device in an electric circuit, such as a battery, switch or lamp. are shown by using standard symbols in circuit diagrams. You need to be able to draw and interpret circuit diagrams.
