Calculate the current through a 60w lamp

WebThe current flowing through an appliance can be calculated using the equation: ... A bed side lamp is rated 60 W, 240 V. Calculate the size of fuse that should be fitted to the lamp for it to ... WebCorrect option is D) P= RV 2. We assume rated voltage of both bulbs is same so R∝ P1. thus, R 40>R 60. As they are connected in parallel so potential across them will be same i.e V. now, power dissipation , P∝ R1. thus, P 60>P 40 as R 40>R 60. Therefore 60 W bulb will give more lights.
