A 50 mH inductance is connected in series with 20 ohm resistor. If the voltage is 220 volts.What power is drawn?
ANSWER QUICKLY
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.
