Physics Lightning is produced when Strong opposite charges in different clouds break down the resistance offered by the intervening air Water vapour produces electricity in the clouds Clouds strike against impurities in air and the friction burns up these impurities Similar charges of electricity rush towards each other and then get repelled Strong opposite charges in different clouds break down the resistance offered by the intervening air Water vapour produces electricity in the clouds Clouds strike against impurities in air and the friction burns up these impurities Similar charges of electricity rush towards each other and then get repelled ANSWER DOWNLOAD EXAMIANS APP
