100
These are the three methods of charging
What is friction, conduction and induction
100
This is the law used to determine forces between charges particles
What is Coulomb's law
100
The law states that current is directly related to voltage but inversely related to resistance
What is Ohm's Law
100
This is constant in a series circuit
What is current
100
When charging an object, these are the particles that move.
What is an electron
200
This method involved contact
What is conduction
200
This is what happens to a force between two charged objects when you double the distance between them.
What is reduce the force by four (or 1/4 F)
200
The unit of current
What is amps
200
This is the overall resistance of a series circuit with three resistors whose values are 12, 8 and 16 Ohms
What is 36 Ohms.
200
Two 4 Ohm resistors are wired in parallel and placed in series with a 6 Ohm resistor. This is the overall resistance of the circuit.
What is 8 Ohms
300
This method will give the object being charged the same sign and the object doing the charging
What is conduction
300

True or false. Electric field lines never cross one another. 





What is true.

300
This is current that runs through a 10 ohm resistor hooked up to a 1.5V battery.
What is 0.15A
300
When adding more resistors in parallel, this is what happens to the current.
What is increases.
300
A balloon sticks to a wall because of this
What is polarization
400
This method involves the use of a ground wire.
What is induction
400
Electric field lines are drawn _________ a negative charge and ___________ a positive charge
What is toward and away from.
400
This is the reason why current flows in a circuit
What is a difference in potential
400
When a light bulb goes out in a series circuit, this is what happens to the remaining bulbs
What is they all go out.
400
This type of charging is why clothes cling together after coming out of the dryer
What is charging by friction
500
This is also know as a separation of charges
What is polarization
500
This is what determines the direction of electric field lines
What is the direction a positive test charge moves
500
This is the current flowing through your 1000W toaster when plugged into your wall socket.
What is 8.33A
500
This is the total current in a parallel circuit that has three 12 Ohm resistors connected to a 24V battery
What is 6A
