1.
A light bulb which is 20Watt, is run for 2 hours
equals to 40Wh, which mean 40Watt used in an hour
is the concept correct?
2.Assume above was correct.
The 20Watt is powered by a battery which is 200Watt.
This battery can last for 5 hours.
IS the concept above correct?
3.
A wind turbine with 8Watt is connected to the battery(200Watt), to charge the battery before the it connected to the light bulb.
The wind turbine is run for 10 hours, what is the watt-hr of the turbine, and the total wattage in the battery after 10hrs.
thanks
