What you'll learn
Current and voltage as distinct ideas, how series and parallel circuits behave differently, and the difference between conductors and insulators, plus basic safety.
- Current is the flow, voltage is the push
- Conductors let current flow, insulators block it
- A series circuit has only one path
- A parallel circuit gives each branch its own path
- More cells in series means more voltage, and a brighter bulb
- More bulbs in the SAME series loop means a dimmer bulb
- Water plus electricity is dangerous because water conducts
