input & output devices Flashcards
input devices put
energy into electronic circuits
all input devices change other forms of energy to
electrical energy
all electronic systems have
inputs and outputs
input devices are used as
sensors in electronic circuits
input device
in a microphone, the energy change is
sound to electrical energy
input device
in a thermocouple, the energy change is
heat to electrical energy
input device
in a solar cell, the energy change is
heat + light to electrical energy
input device
in a thermistor, the energy change is
heat to electrical energy
input device
in an LDR the energy change is
light to electrical energy
output devices take energy
out of electronic circuits
all output devices change electrical energy to
1 or more other forms of energy
output device
in an LED, the energy change is
electrical energy to light
output device
in a buzzer, the energy change is
electrical energy to sound
output device
in a motor, the energy change is
electrical energy to kinetic energy
output device
in a loudspeaker the energy change is
electrical energy to sound
