Electric spark is the electrical discharge when a ___________ electric field creates an ionized channel. Fill in the blank A. Sufficiently strong B. Moderate C. Weak D. Very weak
Hint:Spark is created in the electric field exceeds the dielectric breakdown strength. Increase in ions and electrons cause the air gap in between them to produce electrically conductive is called dielectric breakdown.
Complete answer: Now we can go through the electric spark and at which point it creates an electric field in the ionized channel. Electric spark is the electrical discharge when a sufficiently strong electric field creates an ionized channel. Thus the correct option is a (sufficiently strong).
Electric spark occurs when a hot wire touches the ground or its neutral then it can cause some short circuit, it happens only when an excessive current produces its significant heat.The electric spark has a minimum of $3000$ volts.
Most of the electric sparks occur only when two prong wire can touch the ground and it has some electrical outlets so that the electric spark can cause some fire. Spark plug has more power because the police have used some teasers in short circuits. Due to this only the spark plug may hurt for us when it has some short circuit.
Note:The electrical spark is sufficiently strong in the electric field when it has some electric field in the ionized channel. Thus from the given options the correct option is a. Electric spark occurs in short circuits, overloading and some improper repairs thus it causes some damage when it touches the ground in neutral state.
