- 1AC (alternating current)(Power Supply) Current travels in both directions
- 2DC (direct current)(Power Supply) Current travels only in one direction
- 3Battery(Power Supply) Transforms Chemical Energy to Electrical Energy
- 4Outlet(Power Supply) Stable AC current from the power station
- 5Photoelectric (Solar) Cell(Power Supply) Transforms Light energy to Electrical Energy
- 6Piezoelectric Crystal(Power Supply) Transforms mechanical Energy to Electrical Energy
- 7Thermocouple(Power Supply) Small voltage from heating 2 wires of different material connected at their ends
- 8Fuse OR Breaker(Protection) Opens the circuit in the case of a power surge or short circuit
- 9Single-Pole, Single-Throw Switch(Control) Switch with one hinge and one option
