Is electrical power measured in coulombs?

Answer 1

Yes, it can be measured. Coulombs is a measure of charge. 1 ampere second = 1 coulomb. With DC current you simply multiply your current by time applied. For alternating current you would need to integrate, Although if all you have are data points, (which is more likely) you would probably use Simpson's Rule to approximate the amount of charge. Keep in mind that Coulombs is a scalar quantity (an amount) and Ampere's is a vector quantity. so Ampere has a magnitude and direction.

The other way you can measure Coulombs is to count electrons. take the number of electrons and divide by 6.24e18 (the approximate number of electrons to make a coulomb). But I'm unsure on how to count individual electrons.

Answer 2

No.

Coulombs are a measure of charge - literally electrons, although the whole unit is much larger than a single electron.

In some circuits, such as lithium ion battery chargers, literally measure the amount of current over time which gives you the amount of charge - coulombs - that has passed from the battery into the powered device or vice versa.

All that being said, in this case, the value of the coulombs can be negative. This simply represents a charge imbalance.

Power is measured in Watts. Power can be generated in Watts or consumed in Watts.

Answer 3

No. Electrical power is measured in watts, abbreviated to the upper-case W. Coulomb is a measure of electric charge.
