IT WOULD BE THE SAME!!!

Work would also increase

Slide 16

Electric Potential (volts)

Electric Potential (volts)

Electric potential is associated with LOCATION, not CHARGE

Slide 17

Electric Potential vs Potential Energy

Electric Potential vs Potential Energy

Which charge has more electric potential?

Which has more potential energy?

Slide 18
