How much energy is transferred by a 12 v power supply to each coulomb of charge which it moves
around a circuit?
Answers
Answer:
The answer is 12 joules..
Explanation:
The term each coulomb means Every 1 coulomb. so the charge here is 1 coulomb the potential difference is 12 v. we have to find out the energy.
this energy will be equal to the work done .
Now
Potencial difference= work done / charge moved
or
V= w\q
12= W/1
SO
work done (w) = 12×1 joules .
since the work done on each coulomb of charge is 12 joules, therefore the energy given to each coulomb of charge is also 12 joules........
