A lemon needs to be large enough to generate about 1.5-2 volts of electricity in order to light up a small LED bulb. A regular lemon from the store should be large enough for this purpose.

How many 1.5 volt batteries does take to light up a big light bulb?

Is the bulb a 1.5 volt bulb? A 3 volt bulb? A 12 volt bulb or a 120 volt bulb?Or does it have some other voltage such as 230 volts which is very common in Europe and many other countries of the world?What is the wattage of the "big light bulb"?This question cannot be answered without knowing at least the voltage and the wattage of the light bulb that is being asked about.


How many square feet can a light bulb illuminate?

The coverage area of a light bulb depends on its wattage and type. Generally, a 60-watt incandescent bulb can illuminate around 100-200 square feet, while a more efficient LED bulb of equivalent brightness may light up around 200-400 square feet.


What happens when you put an electric motor with higher resistance and a light bulb with less resistance in a series circuit. does the bulb light up and motor spin. or only the motor spin?

(Another possibility is: Bulb lights up and motor does not spin.)The result all depends on the relative resistance of the bulb and the motor, becausethat determines how much of the supply voltage appears across the light bulb, andhow much across the motor.That's one of the big problems with a series circuit: The performance of one devicedepends on the characteristics of the other devices in the same circuit. If you turnthe light off, the motor can't run at all. If the load on the motor changes, then thelight bulb flickers. And if you change the light bulb and put in one with a differentresistance, then the strength of the motor changes.


Was the Big Bang faster than light?

Yes, the Big Bang was faster than light. During the initial expansion of the universe, the rate of expansion was faster than the speed of light.


What kind of energy is it when you turn on a light?

You must distinguish here between the "input" and the "output" energy. The input energy is often electrical energy, but it can also be chemical energy stored in some derivative of petroleum, for example, such as kerosene. That depends on the type of lamp. The intended output energy, of course, is light, but all lamps produce smaller or larger amounts of heat energy, and in some cases, some noise (sound energy).
