Two bulbs have the following ratings

There are two bulbs marked a V, W b V, 40W. Which has higher resistance? Which one has a higher resistance? Resistance of bulb A is more than that of bulb B. Reason R : For a given potential difference the power consumed in a resistor is inversely proportional to its resistance. Calculate the inductance required for this purpose. Two electric lamps are rated as V,W and V, 40W respectively. Their electric resistances are. Which one is having lesser resistance, a 60W bulb or a 40W bulb? What will be the current drawn by an electric bulb of 40W when it is connected to a source of V? Two bulbs of W and 40W are connected in series. The current through the W bulb is 1A. The current through the 40W bulb will be:.

Which of the following resistors, if connected across a 10 volt battery, dissipated the most power?

Courses for Kids. Free study material. Offline Centres. Talk to our experts Two bulbs 40 W, V and W, V are connected in parallel with volts supply, then A W bulbs glow with more intensity than 40 W.

These questions and solutions are based on past year papers that have come in examinations of ICSE Class Students should understand the type of questions asked and the solutions provided. These board questions are expected to come in the upcoming exams. Short Answer Type Questions I. Answer: The resistance of a conductor depends on the following factors 1. Length of the wire l. Resistance is directly proportional to the length of wire, i. Area of cross-section Resistance is inversely proportional to the area of cross-section i.
