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) 1 MühF 4,7 MühF 47 MühF 220 MühF
Resistors and ist color Codes, Widerstände und ihre Farbcodes
brown black red 1 K Ohm brown black orange 10 K Ohm brown black yellow 100 K Ohm brown black green 1 M Ohm
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)
