100
This is the law of electric charges.
What is opposite charges attract and like charges repel?
100
This is the energy transformation in a light bulb.
What is electrical --> light/thermal?
100

This is the issue with traditional electricity generation.

What is pollution?

100

The unit of measurement for Power 

What are Watts? 

100

A device that changes electric to mechanical energy

What is a motor?

200
This is why insulators do not conduct electricity.
What is they hold their electrons tightly?
200

This device that measures voltage in a circuit

What is a voltmeter? 

200

This is the approximate percent of alternative energy production in Canada in 2021? 

What is approx 20%?

200

The unit of measurement for Energy

What are Joules?

200

A device that turns mechanical to electric energy

What is a generator?

300
This is the difference between amps and volts.
What is amps = current = rate of flow or how much? What is volts = voltage = energy of each charged particle or "push"?
300
This is the device that measures resistance.
What is an ohmmeter?
300
This is using resources at a rate that can be maintained indefinitely.
What is sustainability?
300

The most common form of wasted energy during energy transformations in devices. 

What is thermal energy (heat)?

300

When a soft iron core is inserted into a coil of wire and a current is passed through the wire, a very strong “temporary” magnet is produced

What is an electromagnet? 

400
This is why a rechargeable battery is rechargeable.
What is the chemical reactions can be reversed?
400

This is the steps for converting energy in Joules to kilowatt hours.

What is divide by 1000, divide by 3600?

400

This is the code used by computers to compute all information.

What is binary?

400

The formula for calculating energy effiecency of devices. 

What is output energy divided by input energy times 100? 

400

The most common type of electricity production that has a coil of wire rotating inside a stationary field magnet. The electricity produced by this type of generator changes direction. 

What is an AC generator? 

500
This is the parts and functions of an electrolytic cell.
What is cathode = positive (copper), anode = negative (zinc), and electrolyte solution (acid)?
500

This is the difference between a step-up transformer and a step-down transformer.

What is step-up = increased voltage & more coils on secondary, step-down = decreased voltage & less coils on secondary?

500

This is the alternative energy source that converts gravitational energy of water into mechanical energy, then into electrical energy.

What is a hydroelectricity? 

500

List 4 types of alternative energy? 

What are wind, solar, tides, geothermal, biomass, hydrogen and hydro? (any 4/7)

500

In 1831, the name of the scientist who created the first electricity-producing generator, which could generate electrical current. 

Who is Michael Faraday?
