• Mechanical
• W F x d
• Fluid
• W P x V
• And for Electrical.

• Charge is generally not given in everyday
  problems, but current (amperage) is! (You will
  also need time in the problem as well.)

1 Coulomb (C)
1 Ampere (A)
1 second (s)
1 coulomb 6.25 x 1018 Electrons

How this all ties together?

• 1 volt coulomb 1 Joule
• Now you can relate all areas of work to one
  another using joules as the unifying unit!
