More to the point, how many joules can one get out of a typical 9V battery. This varies somewhat depending upon the load. At low drain currents, (2mA), a typical manganese alkaline 9V battery will provide around 16,000J over its lifetime, assuming it starts out fresh and is discharged to 1V per cell. One can squeeze out a little - not much - more if you run it down to completely dead. At a 10mA draw, you drop down below 15,000J, at 100mA, only about 12,000J. The above is based on discharge curves for Duracell MN1604

How much charge passes through a battery 22.5Volts if the energy expended is 90 Joules?
1 watt = 1 volt-ampere = 1 volt-coulomb per second = 1 joule per secondSo from this I learn out the fact that 1 volt-coulomb = 1 joule. This feels like somethingthat I probably used to know but forgot many years ago. Be that as it may, I'll use it.1 joule = 1 volt-coulomb90 joules = 90 volt-coulombs90 joules = 22.5 volts x (90/22.5 coulombs)90/22.5 = 4 coulombs
How many kilowatts of energy does a hydraulic power unit create?
As far I know, they come in very different sizes and capacities, so even talking about a "typical" power may be misleading.
Does battery room reqire air colling system?
A battery room may not require cooling, but it will require low humidity -- and for that you may need a cooling system or air conditioner.
Is it safe to charge a battery while in use?
This depends on the type of battery. Car batteries are always charged while in use. With other types of batteries, this is not recommended and may result in a battery explosion or damage to the device the battery is powering.
What are the positive effects of nuclear energy?
Nuclear energy may be used to produce electricity and may be used to uplift the space shuttles.Nuclear energy may be used to produce electricity and may be used to uplift the space shuttles.
