Q

Is a chemical combination of two or more
elements. Water is one of the most common compounds
and is made up of two hydrogen atoms and one oxygen
atom.
Ø consists of atoms of two or more different elements boundtogether
Ø can be broken down into a simpler type of matter
(elements) by chemical means (but not by physical means)
Ø has properties that are different from its component

Q

When it attaches to a new one, an
electron from that atom will be
ejected and it will find a new atom
to attach to. The cycle will
continue on and on, and this what
we call electric??

10
Q

It is a difference of potential appears across theface of certain crystal such as quarts, when they are squeezedor stretched. This is called

A

Pressure

11
Q

All electricity in large useful amount is
at present produced by rotating machines working with theuse of magnets. These machines, known as generator, areturned by water power, gas engines or steam engines andsometimes by electric motor.

A

Mechanical Action

12
Q

a buildup of an electrical charge on the surface of
an object.

A

Static Electricity

13
Q

is produced when an electrical
current flows through a simple conductor such as alength of wire or cable, and as current passes alongthe whole of the conductor then a magnetic field is created along the whole of the conductor.

A

Electromagnetism

14
Q

measures how tightly bound an electron is to an atom.

A

Conductivity

14
Q

Elements with high conductivity, which have verymobile electrons, are called ——–These arethe types of materials we want to use to make wires and other components which aid in electron flow.

A

Conductors

15
Q

Materials that have the characters to behave likeconductors, as well as insulators under different conditions, are known as ———-

A

SemiConductors

15
Q

Metric based prefixes used for electrical calculations.

A

Giga = G = 10^9
Mega = M = 10^6
kilo - K = 10^3
hecto = k = 10^2

deci = d= 10^-1
Centi = c = 10^-2
milli = m = 10^-3
micro = µ = 10^-6
nano = n = 10^-9

15
Q

Elements with low conductivity are called——-. ——- serve a very important purpose: they prevent the flow of electrons. Popular insulators include glass, rubber, plastic, and air.

A

Insulators
