100
Difference between static electricity and current electricity.
Static Electric = build up the electrons; Current Electric = pass through to the conductor
100
The flow of electric charge.
What is electric current?
100
What are V, delta E & Q stand for?
What are V = voltage (in volts), delta E = the charge of energy (in joules) & Q = amount of charge (in coulombs)?
200
What does the law of electric charges state?
Like charges repel and unlike charges attract.
200
A force that could either pull the static charges together or push the static charges apart.
What is electric force.
200
Name 3 parts of a circuit,
What are energy source, load and conducting material?
200
the equation to calculate current
What is I = Q/T ?
200
When the cells will do not provide more voltage, but they do provide a greater amount of charge?
What is electric cells are connected in parallel?
300
When two objects are rubbed together.
What is charging by friction?
300
What causes a lightning flash in the sky?
What is the moving electrons flowing between earth and the cloud in attempt to neutralize it.
300
A diagram that is use to represent an electric circuit using stardard symbols to represent the elements of the circut.
What is a circut diagram?
300
What are I, Q & T stand for?
What are I= current(in ampress), Q= the quanity of electroc charge (in coulombs) & T =time(in seconds)?
300
Definition of resistance (R).
What is a measurement of the opposition to the flow of electric current through a cirict?
400
What is charging by induction?
When objects are charged without touching or making any direct contact.
400
What are Electrostatic Precipitators be used for?
Used to remove the ash particles from the smoke.
400
Difference between a primary cell and a secondary cell.
Primary cell - cannot be recharged because the chemical reaction are irreversible; Secondary cell - can be recharged using electricial energy to reverse the chemical reaction
400
Difference between conventional current and alternating current.
Conventinal Current = the direction of the electric current was from the positive terminal to a negative terminal of the energy source; Alternating Current = the negatively charge electrons that flow from the negative terminal to the positive terminal of the energy source
400
The relationship between voltage, current, and resistance of a conductor.
What is Ohm' law?
500
Is oil a good insulator or conductor?
Insulator.
500
What else can Electrostatic Precipitators be used for?
Can be used to remove wood dust in industrial plants and pulp mills.
500
Differece between an electric cell and a battery
What is an electric refer to one cell & battery refer to a combination of two or more electric cell?
500
Difference between series circuit & parallel circuit
Series Circuit = the current goes through each device in sequence; Parallel Circut = the current spilts up and some of the current goes through each device
500
