- 2. 5 c) A light bulb draws a current of 12A when connected to a 24-V battery. Find the bulb's resistance.
Light bulb A is marked "25 W 120 V" and light bulb B "100 W 120 V"; this means that each bulb converts its respective power when plugged into a constant 120 V source, Find the resistance of each bulb, How long does it take for 1.00 C to pass into bulb A? Is this charge different in any way upon its exit from the bulb versus it entry? Explain, How long does it take for 1.00 J to pass...
Two light bulbs both operate on 120 V. Which draws less current a 60-W lightbulb or a 75-W bulb? Which one has the lower resistance?
A 100-W light bulb is connected to a 110-V source. What is the resistance of this bulb?a) 121 Ob) 8.00 x 10-3 Oc) 6.00 x 10-3 Od) 242 Oe) 100 O
You obtain a 50-and a 100-W light bulb. Instead of connecting them in the normal way, you devise a circuit that places them in series across normal household voltage. If each one is an incandescent bulb of fixed resistance, which statement about these bulbs is correct? Both bulbs glow with the same brightness, but more than their normal brightness. The 100-W bulb glows brighter than the 50-W bulb. The 50-W bulb glows more brightly than the 100-W bulb, Both bulbs...
4) a) What is the current in a 75 W the filament of a light bulb when you tum the light on? Electric sockets supply electricity at about 110 V b) How much charge does flow through the filament during 10.0 second? c) How many electrons pass during this time? d) What is the resistance of the filament? e) What is your monthly payment if you keep the light bulb on for 4 hours every day? The cost of each...
