15. 1 volt is equal to __________ per _____________.
16. What is the value of voltage for a Coulomb of charge with a potential energy of 1
Joule?
Answer: ______________
17. What is the value of voltage for a Coulomb of charge with a potential energy of 50

Answer: ______________
18. If you rub a balloon on your hair, the balloon will become __________ charged up to
______________ volts. That would release 1000’s of Joules of energy if the charge
were __________ Coulomb. Since the charge rubbed on hair is typically less than a
_______________ of a Coulomb. Therefore the amount of energy associated with a
charged balloon is very small even though the energy per ___________ is very
______________.
19. High voltage means high energy only when a _________ amount of __________ is
involved.
