100
What is electric current?
Electric current is the flow of electric charge.
100
What is the SI unit for measuring electrical energy?
Joules.
100
Define resistance.
Resistance is a property of some material that slows down the flow of electrons.
100
What is kinetic energy?
The energy that an object has because of it's motion.
200
What is the SI unit for measuring the rate of flow of electric charge?
Amperes.
200
What is the different between am electric cell and a battery?
An electric cell is just one cell while battery is a combination of two or more electric cells.
200
What is a resistor?
A resistor is some sort of material that causes resistance to the passage of an electric current.
200
List 3 types of energy.
Kinetic energy, Nuclear energy, Elastic Energy, Potential Energy, Chemical energy, Electric Energy
300
What is the difference between static electricity and current electricity?
Static electricity stays in one place for some time. Current electricity is when electric charges move.
300
Name 3 parts of an electric circuit.
3 parts of an electric circuit would be: an energy source, a load, and some sort of conducting material.
300
What is resistance measured in?
Resistance is measured in Ohms (Ω)
300
Is it possible for an energy to be potential and kinetic? Explain your answer.
No, because kinetic energy needs motion.
400
How do you form an electric current?
When electrons move through a metal conductor they form an electric current.
400
What are the two types of electric cells?
Primary and secondary.
400
What are resistors used for?
Resistors help control the amount of current in a circuit.
400
What is kilowatt•hour?
A kilowatt•hour is a unit of electrical energy.
500
How many volts are in a regular AC outlet that you would have at home?
About 120 Volts.
500
What part of the circuit converts electrical energy to other types of energy?
The load.
500
What is the formula for R?
R = V/I
500
