When a circuit having large inductance is switched off, sparking occurs at the switch.
Answers
Answer:Because the circuit has high inductance.
Explanation:
Concept introduction:
An electrical conductor's propensity to resist a change in the flow of current through it is known as inductance. A magnetic field is produced around a conductor by an electric current flowing through it. The amount of the current determines the field strength, which follows any variations in current.
Explanation:
Given that, circuit having large inductance creates spark while switching it off.
We have to find, why sparking occurs in circuit with large inductance.
According to the question,
Inductance is a property of wires. When a load is disconnected, the wire's current instantly changes. Inductors are no longer able to pass an abrupt shift in current through them. As a result, air breaks down when a high voltage increases at the wire's open end. There is sparking for this.
The same principle governs how a spark plug works. even if inductance has a larger value.
Final Answer:
Due to large EMF induced set up across the gap in the switch is sparks.
