What is a fuse?
300
The units for current (I).
What are amperes (amps)?
400
This term describes the method which provides a path for a charge to follow so that it prevents a build up of a charge (similar to the pole on top of some buildings to transfer lightning strikes safely to the earth).
What is grounding?
400
This type of charging happens by the transfer of charge between two objects that are touching.
What is charging by contact?
400
This type of current is typical in an outlet.
What is alternating current?
400

400
This is an image of one.
What is an electroscope?
500
This is related to the force that causes electric charges to flow.
What is a voltage difference?
500
This type of charging is the rearrangement of charge in an object due to the influence of another charged object nearby.
What is charging by induction?
500
the formula for Ohms law
What is current = voltage difference / resistance?
500
the formula for electrical energy.
What is electrical energy (in kWh)= electrical power (in kW) x time (in h)
500
The units for resistance.
What are ohms?
600
a closed path that an electric current follows
What is an electric circuit?
600
An electric charge is surrounded by this, which exerts forces on other charges.
What is an electric field?
600
How do batteries produce a voltage difference in a circuit? (do not have to answer in the form of a question; give 90 seconds instead of 30 seconds timer).
Answers will vary must include the following: carbon rod, paste, chemical reaction, and circuit. Example, "the battery's carbon rod completes the circuit, the electrons are transferred between some of the compounds in a chemical reaction within the paste. The carbon rod becomes positive and the electrons accumulate on the zinc, making it the negative terminal. The voltage difference between these two terminals causes a current through a closed circuit."
