Whaaaat!!!! For constant resistance, V/I is a constant. If the voltage drops, the current will too.
Think of it as water (should come easily around here!). Voltage is the pressure pushing the water, resistance is obvious and current is flow rate. Higher voltages (pressures) give higher currents (flow rates). If you increase the resistance, you have to increase the voltage (pressure) or reduce the current (flow rate).
