An instrument for detecting and measuring electric charge.
What is an electroscope?
100
A closed path that electric current follows.
What is an electric circuit?
100
It powers a TV remote.
What is a dry cell battery?
200
The accumulation of excess electric charge on an object.
What is static electricity?
200
Material that allows electrons to move easily.
What is a conductor?
200
Buildings often have "this". It provides a conducting path from the highest point on the building to the ground.
What is a lighting rod?
200
The net movement of electric charges in a single direction.
What is electric current?
200
The unit for measuring resistance.
What are ohms?
300
This surrounds every electric charge and exerts the force that causes other electric charges to be attracted or repelled.
What is an electric field?
300
The reason metals are good conductors.
Why does electrons in metals move more easily?
300
The clouds negative charge reaching the bottom of the cloud facing earth's positive charge, and the force attraction causing "this" to appear.
What is lightning?
300
It has a pump that provides the pressure difference that keeps water flowing.
How is a water pump like an electric circuit.
300
Three ways to increase resistance.
What are (choose 3) using resistors, using thinner wires, using longer wires, or heat?
400
The law that states that charge can be transferred from an object to another, but it cannot be created or destroyed.
What is the definition of the law of conservation of charge?
400
The rearrangement of electrons caused by a nearby charged object.
What is charging by induction?
400
Causes the charges in a stormy cloud to separate.
What is convection current?
400
A force that causes electric charges to flow.
What is voltage difference?
400
This is how a dry-cell battery works.
What is a chemical reaction occurs in the paste, one plate becomes positively charged and the other becomes negatively charged, and the voltage difference causes a current?
500
Clothes in the dryer becoming oppositely charged and cling together.
What is an example of static electricity?
500
The positive electrons on the ground attract the negative electrons in the cloud.
What is lightning?
500
"This" happens when both of the metal leaves in the electroscope is either positively or negatively charged
What is repulsion?
500
Electric charge will only flow here.
What is a closed loop/circuit?
500
All components of a wet cell battery.
What are positive and negative terminals, a lead plate, a lead dioxide plate, a partition, and a battery solution?
