Answer / kondapallisirivarsha

inductance ....since...resistance becomes zero....high
currents flow through the whole circuit...so heavy heat&
sparks r produced

Answer / srikant

When we suddenly switched off a load due to sudden change in current a voltage is developed across the inductor(v=L di/dt). This heavy voltage will ionise the air to make the air as conductor to produce arc in the form of sparking.

Answer / gayathre

As we switch off the circuit, there is a sudden change in the magnetic flux linked with the circuit.This might be the reason for the spark. And this leads to the answer.

Answer / niloy datta

there must b some other reason... because for AC it always
changes from +ve max. to zero and from zero to -ve max. and
with this principle transformer inductor core works with ac
only. So what u indicate by sudden change..
and when the load is switched off, I think it gets infinite
resistance not the zero resistance...
so please clarify..

Answer / sanjay yadav

Well I think the reason of sparking is high resistance in load circuit .forexample:we can practically see in our home that when we connect or disconnect a 2000kw electric heater to electric circuit,a large numbers of sparking occurs because flow of current (electrons )depend upon resistance. When we connect or disconnect a high resistive load,some current electrons misguide and they jump into air and strike to air electrons,and its result is sparking occurs. Inductance is a not a reason for sparking because when we connect a 25kva 3 phase transformer without load on line there is no sparking occurs on terminal,this is my personal experience.
