200
Potential difference is the difference in what kind of energy between two points in a circuit?
Potential energy, duh
200
What does resistance mean?
a measure of how difficult it is to maintain a flow of charge in an electrical circuit
200
What object do circuits usually send energy through?
wire/cable

square or rectangle
300
What do you have to do to a series circuit to be able to measure current
Remove a wire and use the ammeter/multimeter as your wire to run the current through it
300
What happens to the circuit's potential difference when multiple objects are in series
it splits across the objects
300

Current
300
What kind of material is usually used as a conductor?
metal
300

What is the device for opening and closing electrical circuits under normal load conditions.
switch
400
What are the steps that allow you turn the multimeter into an ammeter?
1. Plug the black wire into the bottom port
2. Plug the red wire into the top port
3. Turn the dial to 5 A
400
If R=V/I, What is V equal to?
(Bonus points for which equation manipulation step to use)
V=IR
(Bonus points: Step 3)
400
According to the resistance/resistivity formula, what conductor would be best for a circuit?
(bonus points for why)
A short, thick wire/Low length, high area
(Bonus points: Resistance has a direct relationship with the conductor's length and an inverse relationship with the conductor's cross-sectional area)
400
How do you control a circuit being on or off without breaking it down?
Switch
400

What is wrong with this circuit? (2 possible answers)
The ammeter should not be outside the circuit
or
The ammeter should be a voltmeter
