The relationship between voltage (V), resistance (R), and current (I) is given by Ohm's Law, V = IR. For the first scenario, V = 12 volts, R = 2 ohms, and I = 6 amperes. For the second scenario, we need to find the voltage when R = 4 ohms and I = 5 amperes. Using Ohm's Law, V = 4 ohms * 5 amperes = 20 volts.
