1.6 - ELECTRICAL STUFF

Question 1

Define a sensor

Answer 1

Input devices that take signals from the environment around them e.g. Light and temperature levels and turn them into electronic signals such as current voltage and resistance

Question 2

How are switches described

Answer 2

Either by the number of Polls and throws that they have or by their function. for example it’s a function for example a push to make switch makes a circuit when pressed

Question 3

Define a transistor

Answer 3

Used as either an electronic switch or current amplifier.

Question 4

what does a transistor have?

Answer 4

3 Lea Leeds called the base collector and the mitter. When the voltage at the base reaches approximately 0.6 V current is allowed to flow between the collector and the emitter.

Question 5

What’s an output

Answer 5

They take electronic signals and turn them back into real world signals such as light or sound etc

Question 6

How do buzzers work

Answer 6

They use an internal oscillator to produce different sounds of different frequencies when a current flows through them.
