What can the potentiometer do in the following circuit? (Choose the best answer) 50 ко- + 5v 10 ko potentiometer can turn the current to the motor on or off The potentiometer can change the gate voltage, but not enough to turn on the MOSFET The potentiometer can control the motor speed by increasing or decreasing the current in the motor on an exponential scale The potentiometer does not control the MOSFET, because the variable resistance does not change the gate voltage The potentiometer controls the motor speed by increasing or decreasing the current in the motor on a logarithmic scale M
