The number of electrons flowing through a light bulb each second can be calculated using the formula I = nqf, where I is the current, n is the number of electrons, q is the charge of an electron, and f is the frequency. By rearranging the formula, we get n = I / (q*f). Substituting the values of I, the charge of an electron, and the frequency into the formula will give you the number of electrons flowing through the light bulb each second.
A photocell contains semiconductor materials that generate charge carriers when exposed to light. The photons in the light provide energy to these charge carriers, creating an electrical current as they flow through the semiconductor material. This current can then be used as electrical energy.
A semiconductor material, such as silicon or gallium arsenide, can conduct current when exposed to light. This phenomena is known as the photoelectric effect, where photons of light create electron-hole pairs that can carry electrical charge through the material.
When a charged capacitor is connected to a light bulb, the current flows from the capacitor through the bulb, causing it to light up. Initially, the bulb may be very bright as the capacitor discharges quickly, but as time goes on, the brightness decreases as the capacitor loses its charge and the current flowing through the bulb decreases.
An increase in the current through a bulb will increase its light output because more current means more electrons passing through the filament, which generates more heat and light. Conversely, a decrease in current will result in lower light output as there are fewer electrons flowing through the filament to produce light.

Electric current is the flow of charge from one place to another. Charge is carried by electrons, so current can be defined as the number of electrons per second that pass through a given area.

Take the wattage of the bulb and divide that by the voltage of the bulb. This will give the current the bulb draws. Amps are a measure of charge (electron) at an instant of time through a conductor. In an incandescent bulb the filament is heated by the current and the characteristics of the filament, usually tungsten, is that it gives off light when heated.
An increase in the current through a bulb will increase its light output because more current means more electrons passing through the filament, which generates more heat and light. Conversely, a decrease in current will result in lower light output as there are fewer electrons flowing through the filament to produce light.
In a series circuit, the current passing through each component, like the light bulbs, is the same. This means that both light bulbs would have the same current flowing through them. If one light bulb were to burn out, current flow through both bulbs would stop.
Electrons move across the terminals of a filament in a light bulb in one direction for 1/120th of a second, and they move in the opposite direction for the next 1/120th of a second. Yes, electrons through a light bulb flip direction 120 times every second.
Yes, a circuit with two light bulbs connected in series can light up. Current flows through the first light bulb, then through the second, allowing both bulbs to illuminate. If one bulb burns out, however, both bulbs will go out.
Static charge builds on the clouds. When the charge reaches a high enough level it discharges, sending a large current through the air. The enormous current superheats the air, which expands and contracts (thunder) while it gives off a burst of light (lightning).
