IT WOULD BE THE SAME!!!

Work would also increase

Slide 16

Electric Potential (volts)

Electric potential is associated with LOCATION, not CHARGE

Slide 17

Electric Potential vs Potential Energy

Which charge has more electric potential?

Which has more potential energy?

Slide 18

Is 5000 Volts Dangerous?

Slide 19

Is 5000 Volts Dangerous?

NOPE!

When 1 million electrons are added to a neutral balloon, it has an electric potential of 5000 volts

Slide 20

Potential Difference (voltage)

Difference in electric potential between two points.

Slide 21

Potential Difference (voltage)

Difference in electric potential between two points.

Potential difference between A and B is 0

A

B

Slide 22

Potential Difference (voltage)

Difference in electric potential between two points.

Now there is a potential difference

A

B

Slide 23

Potential Difference

Batteries provide potential difference between one end of the circuit and the other

Slide 24

Potential Difference

Batteries provide potential difference between one end of the circuit and the other

Charges flow from high to low electric potential

Slide 25

Potential Difference (voltage)

Why aren’t birds on power lines shocked?

Slide 26

Potential Difference (voltage)

Why aren’t birds on power lines shocked?

The Potential Difference between their feet is zero! (0 voltage)

Slide 27

Current (I)

Net flow of electrons
