Find the amount of electric charge that flows through the circuit. -CBSE Physics1 AnswerA torch bulb is rated 2.5 V and 750 mA. Calculate (i) its power, (ii) its resistance and (iii) the energy consumed if this bulb is lighted for 4 hours. -2005 CBSE Physic class 101 AnswerIn a drying experiment, the constant rate of drying is found to be 3.6 kg water m^-2h^-1. Dry bulb and wet bulb temperatures of the drying air are 75C and 37C, respectively. Latent heats of vapourization at the dry bulb and the wet bulb temperatures 1 AnswerGive reasons why electric bulb fuses. NCERT SCIENCE CLASS 6TH CBSE 20170 Answer The supply voltage to a room is 120 V. The resistance of the lead wires is 6Ω. A 60 W bulb is already switched on. What is the decrease of voltage across the bulb, when a 240 W heater is switched on in parallel to the bulb ? - physics 20130 Answer When we press the bulb of a dropper with its nozzle kept in water, air in the dropper is seen to escape in the form of bubbles. Once we release the pressure on the bulb, water gets filled in the dropper. The rise of water in the dropper is due to . cbse-class8-physics-20151 AnswerWhich has a higher resistance : a 50 W lamp bulb or a 25 W lamp bulb and how many times ? -2005 CBSE Physic class 101 AnswerChoose the correct answer :The Thin Wire that gives off light in the bulb is a) Electric Cell b) Filament c) Terminals d) None Of The Above -NCERT CBSE CLASS 6TH SCIENCE 20161 Answer Several electric bulbs designed to be used on a 220 V electric supply line, are rated 10 W. How many lamps can be connected in parallel with each other across the two wires of 220 V line if the maximum allowable current is 5 A? -CBSE Physics 1 AnswerAn electric lamp of 100 Ω, a toaster of resistance 50 Ω, and a water filter of resistance 500 Ω are connected in parallel to a 220 V source.
