Diodes and Transistors
Diodes
An electronic component with two electrodes called anode and cathode. Most diodes are with semiconductor materials like silicon.
If the voltage across a diode is negative then no current can flow and we need current for electricity.
Transistors
A semiconductor device that is used to amplify or switch electronic signals to power. This is made of semiconductor materials with at least three terminals for connection to an external circuit.
This measures if current is going around the house, and if it is then there is electricity.
