is a joule a coulomb
Answers. Best Answer: Joules are volt-coulombs; that is, when you put one coulomb of electrons through a potential difference of 1 volt, you do one joule of work on the system.So you find the number of joules of work (or energy put in to the system) by multiplying the number of coulombs by the number of volts.Choice (a) is correct.o you find the number of joules of work (or energy put in to the system) by multiplying the number of coulombs by the number of volts. Choice (a) is correct.
By definition a volt is a joule per coulomb, V=W/Q (V is voltage, W is work done or energy measured in joules, Q is charge measured in coulombs) therefore 1 volt is 1 joule pe â¦ r 1 coulomb of charge (1C of charge is a very large amount to expect to see very small numbers for charge).GB.y definition a volt is a joule per coulomb, V=W/Q (V is voltage, W is work done or energy measured in joules, Q is charge measured in coulombs) therefore 1 volt is 1 joule pe â¦ r 1 coulomb of charge (1C of charge is a very large amount to expect to see very small numbers for charge).
