100
The way of wiring components so the current must split up and flow through one or the other.
What is parallel?
100
A measuring device that ideally has zero resistance
What is an ammeter?
100
This is the unit for potential difference. It is equivalent to J C-1
What is the volt?
100
This is a type of material that does not allow charge carriers to flow.
What is an insulator?
100
The device that dissipates electrical energy as thermal energy due to collisions of the charge carriers.
What is a resistor?
200
The rate of flow of electric charge. It is a vector quantity.
What is electric current?
200
This type of electric cell can be recharged.
What is a secondary cell?
200
This the unit for electric field strength.
What is N C-1 or V m-1?
200
The work done per unit charge to move charge completely around a circuit.
What is emf or electromotive force?
200
The name of the insulating material placed between the two conductive plates of a capacitor
What is the dielectric?
300
The ratio of potential difference across to the current flowing through a conductor?
What is resistance?
300
This is a type of circuit that outputs a fraction of the input potential difference.
What is a potential divider?
300
The unit of electric current multiplied by time in its honorary form.
What is the coulomb?
300
The ratio of electric charge on one side to the potential difference across both.
What is capacitance?
300
This is a device that has a proportional relationship between the potential difference across it to the current flowing through it provided the temperature remains constant.
What is an ohmic device?
400
This is the law that electric charge comes in a smallest size package, the elementary charge (e).
What is the quantization of electric charge?
400
The symbol is this:
What is a potentiometer?
400
The unit for capacitance times resistance in its fundamental form.
What is the second (s)?
400
This is the constant that describes the ease of the electric field in a vacuum. It is used to calculate the effect of a dielectric on capacitance.
What is the permittivity of free space or a vacuum.
400
What real cells have that causes the potential difference available to the external circuit to be lower than the EMF when a current is flowing.
What is internal resistance?
500
This is the percent to which a fully charged capacitor is discharged to in one time constant (t=RC).
What is 36.8%?
500
The electric field between these is uniform in strength (but not really at the edges).
What are two oppositely charged parallel plates?
500
The unit for k, coulombs constant.
What is N m2 C-2?
500
The work done per unit charge to move a positive test charge from infinity to a point in an electric field.
What is electric potential?
500
The change that is made to this circuit to cause the lamp to dissipate more power.
What is decrease the resistance of the variable resistor?
(or decrease the temperature)
