Ohm's Law
What is V = I x R?
100
When bulbs are wired such that when one goes out they all go out.

200
The charge gained by a balloon when it is rubbed on a sweater.
What is negative charge?
200
The unit of resistance.
What is an ohm?
200
For a constant voltage, the relationship between current and resistance.
What is inversely proportional?
200
The effect on resistance when more branches are added in a parallel circuit.
What is decreases?
200
The equivalent resistance of two resistors wired in series compared to the same resistors wired in parallel.
What is greater?
300
The response of objects with opposite charges.
What is attract?
300
For a bulb to light, it needs a battery and wires that make this.
What is a complete path?
300
The measure of electric potential.
What is voltage?
300
When finding the equivalent resistance in this type of circuit, do not add the resistances.
What is a parallel circuit?
300
The black material that separates the 2 parts of a bulb.
What is an insulator?
400
The two ways to transfer charge.
What are friction and contact?
400
The voltage gain across the battery compared to the voltage drop across the circuit.
What is equal?
400
The current that flows through a circuit with a 6 volt battery and three 4 ohm resistors wired in series.
What is 0.5 A?
400
The equivalent resistance of three 15 ohm resistors wired in series.

What is polarization?
500
The current loses this as it flows through the circuit.
What is voltage or electric potential?
