Ohm's law relates the current, voltage, and resistance in a circuit. Use Ohm's law to determine what will happen to the remaining variable if one is held constant and another is changed. Assume that, originally, the resistance is R0, the current is 0, and the voltage is V0. If the original voltage is held constant but the current is doubled, how does the new resistance compare to the original resistance?
