Miscellaneous
100
This part of an atom has a negative charge.
What is an electron?
100
This is a closed loop through which electrical charges flow continuously.
What is a circuit?
100
A material in which electrons cannot move easily from place to place.
What is an insulator?
100
A material in which electrons can move more easily from 1 place to another.
What is a conductor?
100
The closer you get to a charge, an electric field gets __.
What is stronger?
200
This part of an atom has a positive charge.
What is a proton?
200
This type of circuit has only 1 path for electric current to follow.
What is a series circuit?
200
This is the flow of electrical charges.
What is electric current?
200
This is the rate at which electrical energy is converted into other forms of energy.
What is electric power?
200
True/False: Electric fields exist around every electric charge.
What is TRUE?
300
If an atom gains or loses electrons, it becomes this.
What is an ion?
300
True/False: In a series circuit, if a path is broken, the current will no longer flow and the devices in the circuit will stop working.
What is TRUE?
300
The units voltage is measured in.
What are volts?
300
The units electric current is measured in.
What are amperes?
300
True or False: Conductors generally have a much higher resistance than insulators.
What is FALSE?
400
Objects with the same type of charge do this.
What is repel?
400
This type of circuit has more than 1 path for electric current to follow.
What is a parallel circuit?
400
This is a measure of how difficult it is for electrons to flow through a material.
What is resistance?
400
This converts chemical energy into electric potential energy.
What is a battery?
400
The type of metal that has low resistance and is one of the best electric conductors.
What is copper?
500
These can move from atom to atom and object to object.
What are electrons?
500
True/False: Flowing water is a model for electric circuits and electricity.
What is FALSE?
500
This is the process of providing a pathway to drain excess charge into the earth.
What is grounding?
500
This occurs when an imbalance of electric charge builds up on the surface of an object.
What is static charge?
500
Each month we are charged for how many of these we use.
