A high-voltage generator in a school science project produces a potential difference of 2.5 kV between its output terminals.
a. (i) Express this potential difference in volts.
b. (ii) If a total charge of 0.25 C is transferred between the terminals, calculate the electrical work done by the generator.
c. (iii) Suppose the generator were adjusted so that only 40 J of work is done while transferring the same charge. Determine the new potential difference in volts and in kilovolts.
