4. Consider a 60W light bulb plugged into a 120V socket, and a 100W light bulb plugged into another 120V socket Recall that a bulb's brightness is related to the amount of power (in watts) that is dissipated as heat and light. a Through which light bulb is more current passing? b. Which light bulb filament has more resistance? c. If these light bulbs were connected together in series into the same 120V outlet, which light bulb will be brighter?...

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...

A 12-volt battery is connected to two light bulbs, as drawn in
Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2
has resistance 6 ohms. The battery has essentially no internal
resistance, and all the wires are essentially resistanceless,
too.
When a light bulb is unscrewed, no current flows through that
branch of the circuit. For instance, if light bulb 2 is unscrewed,
current flows only around the lower loop of the circuit, which
consists of...

(a) How much current flows in a 100 watt bulb when lit? Assume 120 volts and assume DC voltage. (b) What is the resistance of a 100 watt light bulb when lit? Assume 120 volts and a tungsten filament temperature of 1200° C when lit. (c) How much current flow in the bulb when it is first turned on and the temperature of the filament is 20° C? Use α-5.36 x 10-3 Co.1 for tungsten.
