100

This piece of equipment can open and close to give you control of whether your lights are on or off.

What is a switch?

100

(Double Jeopardy) This circuit has 4 resistors -- One 4 ohm and one 6 ohm resistor in parallel with a 3 ohm resistor. The sum of these are in series to a 5 ohm resistor. If these resistors are hooked up to a 15 V battery, what is the resulting current?

What is 2.05 A?

100

The unit current is measured in.

What is amps (A)?

100
This piece of equipment supplies voltage to the circuit.
What is the battery?
100
This is the unit resistance is measured in.
What is ohms?
200

This piece of equipment has a symbol that looks like a zig zag.

What is a resistor?

200

This type of circuit has two, or more, resistors in a single pathway.

What is a series circuit?

200
The definition of current.
What is the flow of electricity?
200

Describe how voltage works.

It is a push that moves electrons through a circuit.

200

In a series circuit when you add more resistors, this happens to the total resistance.

What is increases?

300

Type of material used for wires that allow electrons to flow.

What is a conductor?

300
In this type of circuit, each bulb has its own pathway to the battery.
What is a parallel circuit?
300
The formula for calculating current.
What is I = V/R?
300

As voltage increases, this happens to the current in a circuit (provided the resistance stays the same).

What is increases.

300

Wires usually warm up because of this reason

What are collisions between electrons and atoms?

400
(Double Jeopardy) This circuit is hooked up to a 13 V battery. The total current is 23.8 amps. There are three branches in parallel, one containing a 1 ohm resistor, one containing a 2 ohm resistor, and one containing a 3 ohm resistor. What is the value of the current passing through the 2 ohm resistor? 

What is 6.5 Amps?

400

This circuit has a 2 ohm resistor in parallel with a 3 ohm and a 5 ohm resistor. What is its equivalent resistance?

What is 1.6 Ohms

400

If you use a 1.5 volt battery and have a resistor with 16 ohms, this is how much current will flow.

What is 0.094 Amps?

400

A circuit has 300.0 mA of current and a resistance of 4.0 ohms. What is the voltage?

What is 1.2 Volts?

400

In an analogy: If a circuit is like a school hallway, resistance is like __________.

What are students in the way in the hallway?

500

Tool used to measure current.

What is an ammeter?
500

In the drawn circuit on the board, this bulb would be the brightest (Hint: all the bulbs have the same resistance and current determines brightness)

What is B4?

500

If you have a string of 50 resistors that each have a resistance of 3 ohms attached to a 12 Volt battery, THIS is the current that travels through each resistor.

What is .08 A

500

A circuit has 600.0 mA of current and a resistance of 5.00 ohms. How many 0.75 volt batteries are needed to power the circuit?

What is 4?

500

Resistance of a material increases as the material heats up because of this reason.

What is that atoms vibrate more which makes it more difficult for electrons to travel through the material?
