There are two kinds of electric charges.
What is positive charge and negative charge?
100
This 'river' of moving electrons, forced to move by an electromagnetic field, is called this.
What is an electric current?
100
The development of this object is as a result of low resistance material getting very hot and glowing.
What is an incandescent light bulb?
100
The most common way to generate electricity is through this reaction.
What is electrochemical reaction?
100
One percent of the world's electricity is produced using this form of energy.
What is wind power?
200
The intensity of the interaction between positive and negative charges is measured by the magnitude of this force.
What is electrostatic force?
200
Materials which are not good at conducting electric current are known as these.
What is insulators (or non-conductors)?
200
This type of filament is a good conductor and does not melt easily. It is enclosed in a glass bulb filled with an inert gas.
What is a tungsten filament?
200
The electric eel generates electricity through this process.
What is bioelectrogenesis?
200
Plants, grown, harvested and processed into ethanol are known as this.
What is biofuel?
300
Two electric charges are of the same type demonstrate this type of force.
What is attractive force?
300
Metals, being good conductors, have this type of resistance.
What is low resistance?
300
The two advantages to the CFL are these.
What is less heat and longer lifespan?
300
Thermal Generation requires the production of this as a result of the burning of fossil fuels.
What is steam?
300
Wind, biofuels and hydroelectricity have this in common.
What is renewable energy source?
400
Materials and objects are made up of atoms and molecules which are normally neutral due to an equal number of these.
What is protons and electrons?
400
Materials whose conductivity is somewhere between insulators and conductors are called this.
What are semiconductors?
400
CFLs contain this toxic substance and must be disposed of carefully.
What is mercury?
400
Nuclear power plants use thermal generation and uranium which decays through this process to create heat.
What is nuclear fission?
400
The Energy Star symbol on a new appliance indicates that the appliance is this.
What is energy-efficient?
500
Small "zaps" and larger "zaps" such as lightning are better known as this.
What is static electricity?
500
The human body can receive a severe, even fatal electric shock because of this component which makes up the human body.
What is water?
500
Light Emitting Diodes or LEDs produce light as a result of this form of energy release.
What are photons?
500
Two thirds of Canada's electricity and 16% of the worlds electricity is produced through this process.
What is hydroelectricity?
500
In 2016 the Darlington Nuclear Power Station will undergo an important project, allowing for an additional 30 years of electricity generation.
What is refurbishment?
