Question: 1. How much work will be done by an electric energy source with a potential difference of 3 kV that delivers a current of 1

1. How much work will be done by an electric energy source with a potential difference of 3 kV that delivers a current of 1 A for 1 minute and 45 seconds?

2. Calculate the potential difference of an energy source that provides 3.4 J for every milli-coulomb of charge that it delivers.

3. The current in a certain conductor is 40 mA. (a) Find the total charge in coulombs that passes through the conductor in 1.5 s. (b) Find the total number of electrons that pass through the conductor in that time.
