Energy and the Environment
100
The rapid release of static electricity when two objects touch each other.
What is static discharge?
100
This method of charging involves rubbing two objects together, causing electrons to transfer from one to the other
What is charging by friction
100
When the circuit is connected and the current is flowing.
What is closed?
100
The flow of electrical charge (electrons) through a conductor.
What is current?
100
The third prong on a plug is there for this important safety reason.
What is grounding.
200
Connecting an object to earth with a conducting wire to mitigate the effects of lightning.
What is Grounding?
200
When a charged object is brought close to a neutral object, they become attracted to one another.
What is charging by induction
200
Another name for Voltage.
What is potential Difference?
200
A way to connect wires where there is only one path for the electrons to move. If one part goes out, the whole path is disrupted.
What is a series circuit?
200
This dangerous situation happens when electricity flows along an unintended path with little or no resistance, often causing sparks, heat, or fire.
What is a short circuit.
300
The largest form of static electricity.
What is lightning?
300
WWhen a charged object touches a neutral object and transfers electrons, it’s called this type of charging.
What is charging by conduction
300
Multiple are put together to make up a battery
What are Cells?
300
A circuit that has multiple paths. Uses fuses and circuit breakers for safety.
What is a parallel circuit?
300
The device that uses uneven heating of a bimetallic strip in order to make it bend.
What is a circuit breaker
400
Three rules that describe the possible behaviours that occur when objects with different charges are brought close to each other.
What are the laws of attraction?
400
This method charges an object without direct contact by rearranging electrons in a nearby object.
What is charging by induction.
400
What is the symbol for a motor in a circuit diagram
What is....
400
Increasing the length of the wire, decreasing the area (thickness) of the wire, increasing the temperature.
What are ways to increase resistance?
400
Before fixing any electrical device, you should always do this to avoid shock
What is unplug it.
500
Materials that offer little, if any resistance to the flow of charges.
What are good conductors?
500
A balloon rubbed on hair becomes negatively charged (the hair becomes +) by this method.
What is charging by friction.
500
Wrapping wires with this to prevent the movement of electricity.
What are insulators?
500
120 V and 10 A are used to calculate resistance. Include the units resistance is measured in.
What is an 12 ohms?
500
This safety device melts and breaks the circuit if too much current flows through it, helping prevent fires and damage.
What is a fuse.
