Electric field of lightbulb

[dowjonez]

what is the electric field 1m away from a 100 watt light bulb




i know that the power of the light bulb 100 watt = volts x amps

so if the light bulb is a standard 120 volts then the electric field would be V / r

im not sure about this because i know the electric field radiating from the light bulb is a wave

The main element in the lightbulb is the filament, with one end being driven with the 120Vrms voltage waveform, and the other end held at neutral (the metal threads end). Since the metal threads are basically at Earth ground potential (actually neutral, but that's close), the majority of the capacitance from the center conductor and the 120Vrms end of the filament will be to the metal threads. What does that tell you about the electric field lines?

and its strength decreases with distance. However, at a distance of 1m, the electric field would be significantly weaker compared to the electric field at a closer distance to the light bulb. This is due to the inverse square law, which states that the intensity of an electric field is inversely proportional to the square of the distance from the source. Therefore, the electric field at a distance of 1m from a 100 watt light bulb would be significantly weaker compared to the electric field at a closer distance. It would also depend on the specific design and materials of the light bulb, as well as any surrounding objects or barriers that may affect the electric field. Further experimentation and measurements would be needed to determine the exact strength of the electric field at this distance.
