The correct answer is: electrons/second
Explanation:
5A current is passing through the copper wire and the light bulb; it means that 5 Coulombs of charge per second is passing through the wire (as current = coulombs/second). To find the electrons per second, the following formula is used:
Electrons per second =
Density is mass over volume:
In your case, mass is 48 grams and volume is 12cm^3
If you put that into the equation, you will get your density:
