Electrical Types
This type of electricity has a steady flow of electrons.
What is current electricity?
This is the formula for resistance.
R = V / I
This is when a material is somewhere between a conductor and an insulator.
What is a semiconductor?
This is the ability to do work.
What is energy?
Coal and natural gas are examples of this type of resource.
What is a non-renewable resource?
This type of electricity happens when there is a charge separation.
What is static electricity?
The circuit voltage with a current of 110 A and a resistance of 7 Ω.
What is 770 V?
These are the four main components for drawing circuits.
What are conductors, sources, switches, and loads?
A thermocouple converts thermal energy into this type of energy.
What is electrical energy?
This type of energy generates approximately 65% of electrical power.
What are fossil fuels?
"Like" charges will do this.
What is repel?
The current flowing through a hairdryer with a power rating of 900 W is plugged into a 120 V outlet.
What is 7.5 A?
All the lightbulbs on a series circuit will do this if another lightbulb is added.
What is dimmer/decreased brightness?
A blender converts electrical energy into this type of useful energy.
What is mechanical energy?
This type of energy uses heat from the Earth's core to generate electricity.
What is geothermal energy?
This device builds up an excess of static charge using friction.
What is Van de Graaf Generator?

What is 1 560 000 J?
This type of circuit is the best for house wiring.
What is a parallel circuit?
This is a split ring that breaks the flow of electricity for a moment and then reverses the flow in the coil.
What is a commutator?
Hydro-power plants use this type of energy to generate electrical energy.
What is gravitational energy?
This pathway allows the flow of electricity.
What is a circuit?
