The current (I) in a wire varies directly as the voltage (v) and inversely as the resistance (r). If the current is 27.5 amps when the voltage is 110 volts and the resistance is 4 ohms, find the current when the voltage is 185 volts and the resistance is 16 ohms. (Round your answer to two decimal places.)amps
