-transducers-μετατροπείς (lightbulbs,speakers,…) other types of energy to electrical (vice versa)
-sensors other forms of energy to electrical
-actuators-ενεργοποιητές electrical energy to forms of energy
circuits move electricity to different conponents
direct current circuits
alternating current circuits
Current measured with Amps A
Voltage measured with Voltage V
Resistance measured with Ohms Ω
led cathode(-)/shorter leg
anode(+) /longer leg
resistor converts electrical energy into heat
switch — switch is closed it will complete the circuit–monentary/pushbuttons
build the circuit
series curcuit
parallel circuit
