DC Circuit Constructor
Build textbook circuits, investigate current and potential difference, and explore component I–V characteristics in real time.
A LEVEL PHYSICS
Start by adding a cell and a lamp, then join their terminals to make a loop.
Selected component
Select a component in the circuit area to reveal its controls.
Circuit I–V characteristics
All current components are shown; coloured points are their live operating points.
Capacitor charge trace
Run the circuit to trace charge against time.
