To shorten the range of the ammeter. B. To shunt current around the meter movement. C. To shunt voltage around the meter movement. D. To limit current at the input of the ammeter.leaving a freevway. Current from the opposite side must travel further, weakening the potential on that side. This creates a potent the motor in that direction, causing the motor to spin. O Only the side where the switch is closed forms a cormplete circuit, so the motor must spin in that direction.
