Draw circuit diagrams by connecting correct symbols with clear branches and measurement points
A circuit diagram represents the topology of components, supply polarity and junctions using standard symbols and straight labelled connections.
Trace a complete path from one supply terminal to the other, place ammeters in series and voltmeters in parallel, and label relevant values.
To measure a lamp’s current and voltage, put the ammeter in the lamp branch and the voltmeter across the lamp.
A voltmeter placed in series can greatly alter or effectively break a circuit; an ammeter across a supply can cause a dangerous short.
