possibly because less appliances and lights are on at night, more energy can go to the fan

When you rotate the handle of the electric generator faster does it deliver more less or the same voltage?
The speed of a generator only effects the frequency. Most generators operate at 1800 RPM. The output voltage is controlled by varying the field excitation voltage.
What are the differences between the parts of a generator and the parts of a motor?
In principle a generator is the same as a motor. In a dc motor the voltage generated by the rotating armature is slightly less than the supply voltage which causes power to flow in from the supply. If an engine is then coupled to the shaft causing it to rotate faster, then it generates more voltage and power flows back into the supply. That is how a motor becomes a generator.
Do smaller wheels go faster?
No, they just rotate at more revolutions that a larger wheel at the same speed.

Is the voltage at night is more and how it is related to parallel network?
It has more relevance to temperature than to parallel network. The resistance of the electric wires is proportional to temperature. At night the temperature is low so the power loss in the wires is also low so v get more voltage at night rather during day timeAnswerThe supply voltage is related to load. The higherthe load, the lower the voltage. At night, the load on the supply system is lower, so the voltage is higher. Regardless of this, the allowable variation in voltage must be maintained -in the UK, that is 230 V (+10% / -6%). Its relationship with parallel circuits is irrelevant.
Will lower DC voltage or higher DC voltage burn out switch contacts faster if current and resistance stay the same?
if there is resistance in the contact surface , it would heat up more with higher voltage .
Why does voltage increase with current with separate excitation?
More current in the field coils means a stronger magnetic field for the armature to rotate in. This causes the output voltage for a generator to increase. For a motor, more magnetic field means that the supply voltage can be matched at a slower armature rotation speed, so the motor runs more slowly but can supply more torque.
Why sound travels faster during night time?
The only reason it would travel faster is if the air was more dense.
Does Venus and mercury spin faster then earth and mars?
Venus and Mercury rotate slowly, much more slowly than Earth or Mars.
Do Jovian planets rotate faster than Terrestrial planets?
No. The length of a planet's year is determined by its distance from its sun. In our solar system all of the Jovian planets orbit farther from the sun than the terrestrial ones and therefore have longer years.
Will a 240 50Hz run on 220 60Hz?
It's OK but if it's a motor it might run 20% faster. It will run faster by 10 Hz and will tend to take more current to deliver the rated KW load, since the rated voltage is 240 but applied voltage is 220Volts
What are the benefits of low voltage lighting?
Outdoor lighting can make any landscape or yard look beautiful, and they can make it more useable at night. The benefits of lower voltage lighting will be seen in your monthly electric bill, especially if you enjoy being outside at night.
