5.1 charge and voltage
1
Q

2
Q
Negative charge
A
Less protons than electrons
3
Q
Neutral
A
Electrons are equal to protons
4
Q
How can you tell when an object is electrically charged (with static electricity)?
A
The object attracts other objects, or sparks jump from it to other
objects.
5
Q
Attraction
A
Negative + positive
6
Q
Repelling
A

7
Q
Voltage
A
is the difference in charge between two objects.
If you connect the object with a wire you will get electricity.
Electrons flow from negative to positive
8
Q
Electrical current
A
the amount of charge (electrons) flowing through the wire per second
9
Q
