Question 20

Electronic components are…

Answer 20

Electronic components can be selected individually and put together to make a circuit. Examples of components include resistors, capacitors, diodes and transistors.

Question 21

Integrated circuits are…

Answer 21

These are miniature circuits etched onto a piece of silicon, often called a chip, fitted inside a protective plastic package and are manufactured in large quantities.
eg as timers, counters, logic gates or operational amplifiers (op-amps).

Question 22

Power supplies are…

Answer 22

Batteries come in all shapes and sizes. They store electrical charge and as we all know when they are put into an electronic device such as a portable radio, they provide the power.

Question 23

Power supplies:

Answer 23

Batteries come in all shapes and sizes. They store electrical charge and as we all know when they are put into an electronic device such as a portable radio, they provide the power.

Question 24

When choosing a battery, what should be considered?

Answer 24

The power requirements of the circuit.
The battery life needed, measured in milliamp hours.
The size, shape and weight of the battery.
The cost of the battery.
Sustainability: could rechargeable batteries be used?
Battery disposal: how will the battery be disposed of at the end of its working life?

Question 25

Resistors are...

Answer 25

Resistors restrict or limit the flow of current in a circuit. The ability of a material or component to resist current flow is measured in ohms

Question 26

What are the 3 main types of restrictors?

Answer 26

fixed resistors variable resistors special resistors, such as thermistors and light-dependent resistors (LDRs)

Question 27

Fixed resistors are...

Answer 27

These are the most common type of resistor. They have three important uses: protecting components dividing voltage between different parts of a circuit controlling a time delay

Question 28

What is the unit of resistance?

Answer 28

The ohm is the unit of resistance. Larger values are measured in kilo-ohms (1000 ohms) and mega-ohms (1,000,000 ohms). Resistors are marked, using a code specified in British Standard 1852.

Question 29

How is Resistance value shown?

Answer 29

Resistance value is shown by a series of coloured bands, read from left to right.

Question 30

LED stands for...

Answer 30

Light Emitting Diode

Question 31

what is a LED?

Answer 31

A light-emitting diode (LED) is a special kind of diode that glows when electricity passes through it. Most LEDs are made from a semiconducting material LEDs can be bought in a range of colours. They can also be bought in forms that will switch between two colours (bi-colour), three colours (tri-colour) or emit infra-red light.

Question 32

Which way do LEDs let the current pass through?

Answer 32

the LED will only allow current to pass in one direction. The cathode is normally indicated by a flat side on the casing and the anode is normally indicated by a slightly longer leg.

Question 33

MDF

Answer 33

MDF or Medium-density fibreboard is a man made wood that is free from natural damages. It has a smooth sanded surface and precision finish.

Question 34

fret(machine) saw.

Answer 34

The fretsaw is a bow saw used for intricate cutting work which often incorporates tight curves. the fretsaw is capable of much tighter and more delicate work.

Question 35

chisel

Answer 35

A chisel is a tool with a characteristically shaped cutting edge of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power.

Question 36

mallet

Answer 36

A mallet is a tool used for imparting force on another object, often made of rubber or sometimes wood, and usually has a relatively large head.

Question 37

Answer 37

A bench hook is a workbench tool used in woodworking to hold a workpiece in place while crosscutting with a hand saw. A bench hook is a simple method used to improve accuracy and safety.

Question 38

hand drill

Answer 38

a hand drill is a small metal blade you turn or twist in order to make a hole or mark in wood.
