either physical or chemical means

A

Element

24
Q

Photo cells are semi- conduction devices which convert light electrical energy directly into
electrical energy. Either sunlight or
artificial illumination may be employed.

A

Light Action

25
Q

It is the building block of life and matter

A

Atom

26
Q

It is a great deal of the world’s
electricity produced by batteries. These devices generate a different potential means of chemical action.

A

Chemical action

27
Q

often described as being either static or dynamic. The difference between the twois
based simply on whether the electrons are at rest
(static) or in motion (dynamic).

A

Electricity

28
Q
  • It is a difference of potential appears across the face of certain crystal such as quarts, when they are squeezed or stretched. This is called piezo-electricity.
A

Pressure

29
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.

A

Compound

30
Q

All electricity in large useful amount is
at present produced by rotating machines working with the use of magnets. These machines, known as generator, are turned by water power, gas engines or steam engines and sometimes by electric motor.

A

Mechanical Action

31
Q

The number of _______ determine what element that object is made of.

A

Protons

32
Q

Two dissolution metals bonded together in a
junction when heated, exhibits a different potential. This
bond is called thermocouple. Electricity generated by heat
action is called thermoelectric.

A

Heat Action

33
Q

is a property of a material.

A

Conductivity

34
Q

Materials that have the characters to behave like conductors, as well as insulators under different
conditions, are known as ________.

A

semi-conductors

35
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 fieldis
created along the whole of the conductor.

A

Electromagnetism

36
Q

Elements with high conductivity, which have very mobile electrons, are called?

A

Conductors

37
Q

There is only one
__________
in the outermost
shell. (Conductors)

A

valence electron

38
Q

The small magnetic field created around the conductor has a definite direction with both the “_____” and “_____” poles produced being determined by the direction of the electrical
current flowing through the conductor.

A

North and South (electromagnetism)

39
Q

How many zeros in kilo (k)

A

3

40
Q

micro zeros (u)

A

6 zeros (10^-6)

41
Q

serve a very important purpose: they prevent the
flow of electrons. Popular insulators include glass, rubber,
plastic, and air.

A

Insulators

42
Q

These are the types of materials we want to use to make wires
and other components which aid in electron flow. Metals like copper, silver, and gold are usually our
top choices for good _______.

A

Conductors

43
Q

Some elemental types of atoms are better than others at releasing their electrons. To get the best
possible electron flow we want to use atoms which don’t hold very tightly to their valence electrons. An element’s conductivity measures how tightly bound an electron is to an atom.

A
