5. When a light bulb is connected to a 4.5 V battery, a current of 0.16A passes through the bulb filament. What is the resistance of the filament? What is the power delivered to the light bulb? (5pts)
Light bulb 1 operates with a filament temperature of 2600 K, whereas light bulb 2 has a filament temperature of 1900 K. Both filaments have the same emissivity, and both bulbs radiate the same power. Find the ratio A1/A2 of the filament areas of the bulbs.
20. GO Light bulb 1 operates with a filament temperature of 2700 K whereas light bulb 2 has a filament temperature of 2100 K. Both fila ments have the same emissivity, and both bulbs radiate the same power. Find the ratio A/A2 of the filament areas of the bulbs.
Light bulb 1 operates with a filament temperature of 2400 K, whereas light bulb 2 has a filament temperature of 1600 K. Both filaments have the same emissivity, and both bulbs radiate the same power. Find the ratio A1/A2 of the filament areas of the bulbs. A1/A2= Number Units
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 voltmeter connected across the terminals of a tungsten-filament light bulb measures 117 V when an ammeter in line with the bulb registers a current of 0.641 A. a) Find the resistance of the light bulb. (Enter your answer in ohms.) b) Find the resistivity of tungsten (in Ω · m) at the bulb's operating temperature if the filament has an uncoiled length of 0.593 m and a radius of 2.33 ✕ 10−5 m.
The filament of a light bulb is a resistance in the form of a thin piece of wire.The wire becomes hot enough to give off light due to the current in it.A flashlight uses two batteries 1.5 v each to provide a stream of 0.40 in the strand. Determine the bright filament resistance.
When a lightbulb is turned on, 8.90 C of charge pass through the filament of the bulb in 15.0 s. How many electrons pass through the filament in 7.5 s? (Enter 3 significant number in exponent notation: example 1.02e21)
