### 34 Terms

1

Electricity

refers to the flow of electrical power or charge

New cards
2

Circuit

the path where electric current flows on

New cards
3

Closed Circuit

a complete circuit in which electric current flows, "on"

New cards
4

Open Circuit

no current flows, the path is incomplete, "off"

New cards
5

Complete Circuit

- Wire
- Control
- Voltage

New cards
6

Types of Electricity

- Dynamic Electricity
- Static Electricity

New cards
7

Dynamic Electricity

A set of physical phenomena associated with presence and motion of matter.
- All phenomena are related to electrical charges in motion.
- It requires electrical material to make electrons move in a circuit

New cards
8

Two Types of Dynamic Electricity

- Direct Current (DC)
- Alternating Current (AC)

New cards
9

Direct Current

- The electrons always flow in one direction at any time.
- The voltage is always constant in this current.
- Dry cells/Batteries are the source of energy in this current.
- Flashlights, Phones, Laptops, Remote, Clocks are examples of this current.

New cards
10

The other term for potential difference

Voltage

New cards
11

Alternating Current

- The flow of this current moves back and forth with the changing magnetic field.
- This is the type of electricity from wall sockets in your home.
- E.g. air conditioner, motor

New cards
12

Frequency

refers to the changes of direction in one second

New cards
13

Static Electricity

- This type of electricity is build-up of electric charge on an object.
- It is a charge that does not move or flow.
- This energy produces through friction

New cards
14

Electric Charge

It is referred to as the basic property of protons and electrons

New cards
15

Protons and Electrons

It has a property of electric charge

New cards
16

Electric Discharge

The loss of static electricity as electric charges move in an object.

New cards
17

Positively charged

It is the term when an object loses electrons

New cards
18

Negatively charged

It is the term when an object gains electrons

New cards
19

Primary source of our energy today

generator or dynamo

New cards
20

Secondary Energy Source

Produced by converting primary sources of energy such as coal, natural gas, nuclear energy, solar energy, and wind energy, into electrical power.

New cards
21

Dry cell and Battery

are made up of chemicals that could produce electricity.

New cards
22

Electrode

a conductor through which electricity enters or leaves an object, or substance.

New cards
23

Electrolyte

a liquid or gel which contains ions and can be decomposed by electrolysis, e.g. that present in a battery.

New cards
24

Photo voltaic cell

device that converts sunlight into electricity

New cards
25

Piezoelectric Effect

electricity generated by applying pressure

New cards
26

Generator

a device that uses electromagnetic induction to convert kinetic energy into electrical energy

New cards
27

thermocouple

a device that indicates and control the heat of electric oven and furnace

New cards
28

potential difference

will develop if two metals were twisted and heated

New cards
29

Electromagnetic waves

created as a result of vibrations between an electric field and magnetic field

New cards
30

Electromagnetic Field

a classical field produced by moving electric charges

New cards
31

Electrodynamics

study of phenomena associated with charged bodies in motion and varying electric and magnetic fields

New cards
32

Electromagnetism

a term where the electromagnetic force is carried by electromagnetic fields composed of electric fields and magnetic fields

New cards
33

Magnetic Force

a term where it acts between two magnetic objects

New cards
34

Electrical Safety Tips

- Take care of yourself
- Choose the right tools
- Observe exceptional housekeeping
