Final answer:
To make voltage the subject of Ohm's law, the formula I = V/R is rearranged to V = IR. When I is 2 amperes and R is 6 ohms, the voltage is found to be 12 volts.
Step-by-step explanation:
The formula given is Ohm's law, which relates current (I), voltage (V), and resistance (R): I = V/R. To make voltage (V) the subject, multiply both sides of the equation by resistance (R), yielding V = IR. When current I is 2 amperes and resistance R is 6 ohms, we find the voltage by plugging in these values into the rearranged equation: V = 2 A × 6 Ω = 12 volts.
