6. How do the number of electrons flowing into a light bulb compare to the number of electrons flowing out of it?
Number of electrons flowing into light bulb must be equals to number of electrons flowing out of it.
Explanation - The same amount of current flows out of a battery or light bulb as into it.As we know that the current is the number of electrons flowing through a circuit per second and also electrons do not accummulate in any part of the circuit, therefore, the outflow must be equal to the inflow of light bulb

A light bulb connected to a 9-V battery has a current of 1.5 A flowing. Find the resistance of the light bulb (in ohms) Find the power drawn by the light bulb (in W)
Compare the light emitted by the gas tubes with the light elitted by incandescent light bulb.
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...
Two light bulbs are placed side by side. The first light bulb emits red light of wavelength 700 nm, and the second light bulb emits violet light of wavelength 400 nm. (a) Fill in the blanks in each of the following statements with the word greater, the word smaller, the phrase the same, or the phrase don’t know. (i) Compared to the photons of red light, the photons of violet light have __________ frequency. (ii) Compared to the photons of...

Compare the resistance of a 1.5-Amp interior light bulb of a car (operating off a 12-V battery) to the resistance of a 100-Watt bulb operating on a 110-volt household circuitry.
A circuit consists of a 3-volt battery; connecting wires with very low resistivity; a light bulb with resistance = 2Ω. a. How much current is flowing through the bulb? b. How much energy per second is converted from electrical potential energy to light and heat? c. If the bulb is replaced with one with higher resistance, in what way (increase, decrease, stay the same) would voltage and current change?
Imagine that you turn on the lamp in your room that contains an incandescent light bulb and that you stand 1m from the light. Suppose further that your bulb is rated at 100 W. What is the intensity of the light that passes out through this sphere at this distance of say 1m? Now compare this to a milliwatt laser at the same distance away. How many times more/less intense is the laser beam to your eye compared to the...
Question 33 (6 points) 33. A light bulb emits light uniformly in all directions. If the peak electric field of this light is 16 N/C at a distance of 1.35 m from the bulb, (a) what is the average power radiated by the bulb? (b) What is the peak magnetic field B at that distance?
