Current Pathway
Path for electrons to flow.Instructions
- Click directly on the switch in the circuit diagram to open/close it.
- Click on the bulb to change its brightness level (resistance changes).
- When circuit closed, current flows and bulb lights up.
- Open circuit: no current, bulb off.
- Change voltage to see Ohm's Law in action (I = V/R).
