100
Lightening is an example of this.
What is electrical discharge?
200
This part of an atom is positively charged.
What is a proton?
200
The higher this is, the lower the current.
What is resistance?
200
Calculate the current if the voltage is 120 V and the resistance is 6 ohms.
What is 20 A?
200
This is the switch that automatically opens if the current is too high.
What is a circuit breaker?
200
This is the force between two objects.
What is electrical force?
300
This method of charging occurs when there is not direct contact between two objects.
What is induction?
300
As this increases, so does the current.
What is voltage?

300
This is the region around a charged object where a force is exerted on other objects.
What is electric field?
400
Protons are electrons are attracted to each other because:
What is protons have a positive charge and electrons have a negative charge?
400
This generates electrical energy from chemical energy.
What is a cell?
400

400
In this circuit the components are connected in a single loop.
What is a series circuit?
400
Clothes often stick together because of this.
What is static electricity?
500
It is important that electrons and protons are attracted to each other because
What is to keep electrons from flying away from the nucleus?
500
The size of an electric force depends on which two things?
What are the amount of each charge and the distance between the charges?
500

What is 0.375 kWh?
500
In this circuit the components are connected in a side-by-side pattern.
What is a parallel circuit?
500
This device uses the temperature difference in wires to convert thermal energy into electrical energy.
