The relationship between voltage (V), resistance (R), and current (I) is given by Ohm's Law, V = IR. For the first scenario, V = 72 volts, R = 9 ohms, and I = 8 amperes. For the second scenario, we need to find the voltage with R = 5 ohms and I = 2 amperes. Using Ohm's Law, V = 5 ohms * 2 amperes = 10 volts.
