Answer 0

Work = force times distance

Question 1

What is current in terms of charge?

Answer 1

I = charge / time

Question 2

What is volts in terms of work?

Answer 2

Volts = work / charge

Question 3

What is power in terms of work?

Answer 3

Power = work /time

Question 4

What is power in terms of volts?

Answer 4

Power = volts X amps

Question 5

Explain why power equals volts by amps?

Answer 5

Power = work / time
Volts =. Work / charge
Amps = charge / time
(Work/ charge) X ( charge / time) =(work / time)
