Sparking occur when a load is switched off because the
circuit has high
a.) Inductance b.) Capacitance c.) Resistance
d.) None
Answer Posted / 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.
