Electronics

Question 1

Sensors (input components)

Answer 1

A sensor is affected by the conditions around it

Gives a input signal to electronic system

Question 2

Switches (control/process/input)

Answer 2

Allows or prevents electrical power from flowing round a circuit
For any device that’s need power to turn on and off

Question 3

Examples of sensor

Answer 3

Light dependent resistor
Thermistors
Piezoelectric sensors

Question 4

Control/process components examples

Answer 4

Switch
Resistor
Programmable components

Question 5

Thermistor( input component)

Answer 5

Resistance of it changes as temperature changes
Change in resistance can be used as a an input
For fridges, freezer, central heating system to maintain temps

Question 6

Piezoelectric sensor (input component)

Answer 6

Can change mechanical motion or force into electrical energy
It can produce an electrical pulse from pressure such as by hitting it
For igniting lighters, portable camping stoves and in microphones (where sound waves create pressure that makes the electrical pulse)

Question 7

Resistor (process/control component)

Answer 7

To limit/control the flow of current
Have a tolernenxe of how much current they allow in a circuit and resists currebt flow if it goes out of tolerance
For all electrical products - it helps to control the flow of current and protects delicate components bring overloaded. Prevents damage to components

Question 8

Programming components (process/control device)

Answer 8

Chip that can be programmed to make decisions based on an input
For most modern electrical products (e.g washing machines are programmed to work when the drum door is shut and the on/off button is pressed)

Question 9

Output components examples

Answer 9

Loudspeaker
Motor
Light emitted diode (LED)

Question 10

Loudspeaker (output device)

Answer 10

Uses pulses of eelxtricity to move electromagnet that vibrates to create a sound
For speakers headphones and radios

Question 11

Motor output device

Answer 11

Convetsbpower into a rota ray motion that can turn a spindle linked to gears or wheels to make them move
For cars and trains

Question 12

Light emitting diode (output decided

Answer 12

Gives our Kruger when electricity is passed through it
Long lasting low power light
For torches, lamps, power indicators

Question 13

Buzzers

Answer 13

Makes a sound

For in a sensing device to notify people of a warning or something that needs their attention
