I give a simple example,suppose mujhe ek big water tank mein pani bharna hai.big water tank ko bharne ke liye mote pipe ki jaroorat hogi.pani uper tank tak le jane ke liye ek electric motor ya engine ki jaroorat hogi.jab motor on hoga tab tank bharna suru ho jayega.chalte huye motor me agar hamne tank ko bharne ke pipe ko suddenly nikaal diya jaaye our dusre paani ke tank se jod dia jaaye ,toh pahle tank me paani ko bharne walla pipe me (between tank to motor)Jo pani hoga back pressure me vaapas aayega our ground per spread ho jayega.in this example water tank as a load,every load including coils also have its own resistance.tank size is as a resistance and storage water is as current,pipe is as conductor,flowing water in pipe is as current pipe disconnection point is as switch and the motor fan who lift the water work as a emf and the motor is as supply generator.I think u all better understood.mai reason is current.
