100
The force between charged object.
What is electric force?
100
Ampere (A)
What is the unit for electric current?
100
Resistance in a circuit is equal to voltage divided by current.
What is Ohm's law?
100
Watt (W)
What is the unit power is measured in?
100
A material which charge can easily flow through.
What is a conductor?
200
Charging by induction, charging by polarization, charging by friction, and charging by conduction.
What are the four ways charges can redistribute themselves?
200
The atoms in conductors have loosely bound electrons that can move freely. The electrons in insulators cannot move freely among atoms.
What is the difference between conductors and insulators?
200
Found that current, voltage, and resistance in a circuit are always related in the same way.
What is what did Ohm discover?
200
The fuse melts
What is what happens when a fuse gets too hot?
200
Connects the metal parts of appliances to the building's ground wire.
What is third prong?
300
Charges that are the same repel each other. Charges that are different attract each other.
What is how do charges interact?
300
The difference in electrical potential energy per charge between two points in a circuit.
What is voltage?
300
All the parts are connected one after another in one long path. Single path for current.
What is series circuit?
300
Devices that redirect current or break circuits Hint : What does this help?
What is how can electric shocks be prevented?
300
Different parts of the circuit are on separate branches. There are several paths from the battery and back to the battery.
What is a parallel circuit?
400
Charges are neither created nor destroyed.
What is the law of conservation of charge?
400
It is affected by the energy of the charges and the properties in the objects that the charges flow through.
What is current flow?
400
All electric circuits have these basic features: devices that run on electrical energy, sources of electrical energy, and conducting wires.
What is a circuit made of?
400
The more power rating an object has, the faster it transforms electrical energy.
What is how does power rating relate to it's electrical energy?
400
When a metal object is close to a negatively charged object,electrons are repelled by the field and move away from it. The close end of the metal object becomes positively charged. The opposite happens if the other object is positively charged.
What is induction?
500
Lightning bolts are an example of static discharge. Electrons move from areas of negative charge to areas of positive charge, producing an intense spark.
What is how lightning occurs?
500
When electric charges are made to flow through a material.
What is how an electric current os made?
500
A series circuit has one path while a parallel circuit has two. If a parallel circuit has a light or resistor, or anything that goes out, it can continue to run because there are other pathways for it to take. If anything goes out in a series circuit, everything stops because there is only one path that it is able to take.
What is the difference and similarities between series circuits and parallel circuits?
500
The total amount of energy used is equal to the power of the appliance multiplied by the amount of time the appliance is used.
What is how is electrical energy bill determined?
500
The electrons react to electric fields, resulting in individual atoms having charged ends that are attracted to charged objects.
What is polarization?
