100
Based on the photo below, what is the balloon? 
Negatively charged
100
This safety device melts and breaks the circuit when too much current flows.
What is a fuse?
200
Static electricity is a contact force.
True or False?
False
200
In a circuit, what is the object that takes in and uses the electrons?
Load
200
When you know the current and the voltage, which variable are you looking for in Ohm's law?
Resistance
200
Using the electrostatic series, which item/ material would hold the highest number of electrons when charged?
Ebonite
200
This instrument measures electric current and must be connected in series.
What is an ammeter?
300
This material allows electricity to flow easily, such as copper or aluminum.
What is a conductor?
300
In a circuit, what item can allow or prevent the flow of electrons?
Switch
300
What is the formula used when solving for current using Ohm's Law?
I = V / R
300
What would happen to the hairs on your head if all of them were positively charged?
They would repel one another
300
This is the name for materials that resist the flow of electricity, like rubber or plastic.
What is an insulator?
400
When electrons flow inside a circuit, what way do they flow?
From the negative side/ terminal of the battery to the positive side/ terminal.
400
When a circuit is considered "open" what does this mean?
The circuit is incomplete and does not allow for electron flow. (A switch is off/ disconnected or there is not a completed set of wiring/ conductors allowing for electricity flow)
400
What form of measurement represents the pressure pushing electrons through a circuit?
Voltage
400
When an object gains electrons from touching something that is negatively charged, what type of charging is this?
Conduction
400
This rule of electricity states that opposite charges attract and like charges repel.
What is the law of attraction?
500
Explain the process of static electricity.
Static charge, or electrons, build up on one surface and stay there until they are given an opportunity to release, or discharge onto an opposingly charged or neutral surface.
500
What is a short circuit?
Energy ends with the battery. No load. Can cause fires.
500
Solve the following equation. You MUST use units.
What is the current produced by a voltage of 120 volts through a resistance of 0.5 Ω?
240 amperes/ amps
500
What is the process called AND what is the special wire used to reduce excess electrons?
Grounding and ground wire
500
If a circuit has 9 V of voltage and 3 A of current, this is the resistance.
What is 3 ohms?
