What is the current through a wire when 20C passes a point in 2 s

What is 10A?

100
The unit of voltage.
What is Volt?
100
The SI unit for power
What is Watt?
100
The kind of circuit in which all resistors are on one continuous unbroken path
What is a series circuit?
100
The area around an electrically charged object is referred to as this.
What is the Electric Field?
200

As the length of a wire increases the Resistance

What is increases?

200
The unit of electric current.
What is Amp(ere)?
200

The equation(s) for electric power.

What is P = IV?
P=I2R
P=V2/R

200
In a parallel circuit, this is what is always the same for each branch.
What is the voltage drop?
200
The person who decided that the charge of the electron should be defined as negative, which in retrospect was really a bad idea because it messed up the definition of current. (That's probably why no one liked him and he was never elected president.)
Who was Ben Franklin?
300

Making a wire very hot will do this to resistance

What is increase?

300
The equation for Ohm's Law.
What is V = IR?
300
The power given off by a 9V battery which is sending out 3 Amps of current.
What is 27 Watts?
300
The total resistance in a series circuit containing a 4 Ohm, an 8 Ohm and a 10 Ohm resistor.
What is 22 Ohms?
300
What AC stands for with respect to electricity.
What is Alternating Current?
400

How many electrons pass a point in 2s if the current is 0.8A?

What is 1 x 1019

400

What is the the total voltage of a series circuit where the potential difference of R1 is 10V, R2 is 5V and R3 is 1V?

What is 16V

400
The standard SI unit of energy.
What is Joule?
400
Parallel circuits often contain one of these, a device which closes the entire circuit in case the total amount of current becomes dangerously high.
What is a circuit breaker? (Or, what is a fuse?)
400
He designed the first AC motor, better light bulbs than Edison's, and a method to transmit electricity without the use of wires, but despite the film The Prestige, he didn't invent a cloning machine.
Who is Nikola Tesla?
500

A current is traveling north through a wire. It creates a magnetic field that is going in which direction the the right of the wire?

What is into the page?

500
The phenomenon where some materials have a resistance of exactly zero at very low temperature.
What is superconductivity?
500
Electric utilities charge for energy using this unit, not the standard SI unit.
What is kilowatt-hour?
500

A 10 ohm resistor is connected in series to two 20 ohm resistors in parallel. What is the equivalent resistance?

What is 20 ohms?

500
The name for the wire inside a light bulb that glows to give off light.
What is the filament?
