Physics Suppose voltage V is applied across a resistance R. The power dissipated in the resistance is P. Now the same voltage V is applied across a parallel combination of three equal resistors each of resistance R. Then the power dissipated in the second case will be 3P 2p/ 3 P/3 P 3P 2p/ 3 P/3 P ANSWER DOWNLOAD EXAMIANS APP
Physics Lightning is produced when Strong opposite charges in different clouds break down the resistance offered by the intervening air 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 Water vapour produces electricity in the clouds Strong opposite charges in different clouds break down the resistance offered by the intervening air 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 Water vapour produces electricity in the clouds ANSWER DOWNLOAD EXAMIANS APP
