- BASICS
DC Direct Current Gleichstrom
AC Alternate Current Wechselstrom
- Ohm's law Ohmsches Gesetz
R = U/I U = R*I I = U/R
R - Resistance, Widerstand Ohm
U - Voltage, Spannung V
I - Amperage, Stromstärke A
- Capacitor/Condensor, Kondensator
-used to store energy electrostatically in an electric field
- Speichern von elektrischer Ladung und damit zusammenhängender Energie
- Electrolytic Capacitor, Elektrolyt-Kondensator
- same function as the usual capacitor, only use with DC - Anode and Kathode → polarised
F - Farad - electric capacity, elektrische Kapazität Müh - micro, mikro
0,01MühF (103)

- LED
LED - Light Emitting Diode ↔ (regular) Diode
always connected to a resistor as it does not need
as much current as the other parts of a circle
→ resistor with 1 K Ohm (brown black red)
