Voltage
Current
Resistance
Inductance
We discussed that when the Van De Graaff was turned on it delivers a bunch of electrons to the big sphere. Since there are a bunch of negative charges pushed into this space...
The electrons (-) would be more strongly to the protons (+)
The electrons (-) would be repelling each other
The electrons (-) would be attracting each other
After a couple seconds of the Van De Graaff running, there is a high voltage between the sphere and the ground. Why?
All the electrons on the sphere are repelling each other; the ground is a place they could get farthest from each other
When current flows it makes a voltage appear due to the resistance of the charges
The protons in the ground really want to be up on the sphere.
Why does the spark from the Van De Graaff jump several centimeters through the air when you get close... yet you can get super close to an outlet and there is no spark?
The voltage for a household outlet is not as high as the voltage on the Van De Graaff
The current isn't high enough in a household outlet to jump through the air
The Van De Graaff has such a large resistance that charges can jump
Which attempt would light the bulb?
(look at the pictures carefully)
B
C
D
E
None of the above
positive
negative
neutral or zero
opposite
Angel touches a dome of Van de Graaff while standing on a plastic stool to insulate her from the ground. Her hairs stand upright because...
Extra electrons from the Van de Graaff are trying to get out away from the sphere.
Extra electrons from the Van de Graaff build up everywhere, including her hair, and since electrons repel each other, her hair strands repel each other.
Touching the Van de Graaff makes air molecules want to get closer to the dome so they move through her body.
The flow of electrons (electricity) always flows from _____ areas to _____ areas.
positive, negative
negative, positive
positive, neutral
neutral, negative
The flow of electrons is called ______
Current

The closer two charges are to each other the _____________ the electric force
weaker
less
stronger
stretched
