In practical terms, no.
Experiments show that the available current is less than 20 milliamps, at a voltage of a volt or less.
This may be enough to make a high-efficiency light-emitting diode glow, but "light bulb" implies an incandescent (filament in glass) lamp, and the available power is insufficient.
There is a workaround - use a "lemon battery" to charge a high-capacitance capacitor (a one farad "super-capacitor"), then use the super-capacitor to drive the light bulb as it discharges.
The Science Writer in me gets a bit frustrated at the numbers of books (science, hobbies and others) that continue to show this as a practical exercise.
This writer also gets *very* grumpy over the books (nearly *all* of them) that show the Bernoulli effect (high-speed airflow over the top of the wing) as the sole mechanism producing lift in an aerofoil (!)
The citrus inside of it.
Electricity is the source of energy in a light bulb.
The citric acid inside in a fruit could make it work. Fruits that is part of the citrus family has a contains a citric acid. For example a lemon, it could make a light bulb work. :)
Could be a light bulb, but traditionally it's sunlight via a mirror.
It is a source of light only.
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.
nope but a potatoe can im not sure its a fruit
An incandescent bulb is 96% efficient as a heater, and 4% efficient as a source of light. A fluorescent bulb is only 60% efficient as a heater, and 40% efficient as a source of light. An LED bulb is only 10-20% efficient as a heater, and 80-90% efficient as a source of light (but that light is usually unidirectionally directed... harder to do diffuse lighting with them).
yes
Yes, that is a "conventional" source of light.
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.
The bulb converts energy from the power source into light and heat. It is the load in the circuit.
