1.    A resistor of resistance 2.5kΩ has a voltage of 75V applied across it. What is the current through it? (Give your answer in amperes.)
2.    How much energy does a resistor dissipate if a potential difference of 9V is applied to it for 5 minutes, and a current of 0.10A flows through it?
3.    If a charge of 3 MC (MegaCoulombs) is moved through a potential difference of 15GV (GigaVolts), how much energy is transferred?
