A 15-W compact fluorescent light bulb is used in a lamp plugged into a 120-V wall socket. You can assume the lamp itself has zero resistance. Find (a) the resistance of the light bulb, (b) the maximum current through the bulb, and (c) the maximum power used by the light bulb. Also, if the frequency of the electricity is the typical household value of f = 60 Hz, what are the first two times that the current going through the...
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...
