At the fastest speed all the drop is across the motor but as you increase the resistance with the speed coil the voltage left for the motor becomes less and less. Since the circuit is effectively a constant voltage device, as you increase the resistance with the speed coil the current must decrease i. e. E(12 volts) = IR. Thanks.
When you figure it out post those run times.
