WebQUESTION BANK ON CAPACITANCE QUESTION FOR SHORT ANSWER Q.1 The electric strength of air is about 30, 000 V/cm. By this we mean that when the electric field intensity exceeds this value, a spark will jump through the air. We say that “electric breakdown” has occurred. Using this value, estimate the potential difference between … The most spectacular form of ESD is the spark, which occurs when a heavy electric field creates an ionized conductive channel in air. This can cause minor discomfort to people, severe damage to electronic equipment, and fires and explosions if the air contains combustible gases or particles. However, many ESD events occur without a visible or audible spark.
