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.
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.
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.
How many watts are in defibrillator?
The AED output is in joules (J); an energy output. Energy is an Amp Ohm divided by time. Although AED's may vary on their output, depending on numerous criteria, some AED's will shock at 200J, then 300J, then 360J.
What type of energy is measured in joules?
All types of energy may be measured in Joules.
Batteries are what kind of energy?
A battery is not a type of energy. It may CONTAIN chemical energy, if it is loaded.
Work may be measured using units of?
Answer #1: Joules (J) or Newton metres (Nm)==================================Answer #2: Energy
How do you describe energy in your own words?
Energy is the ability to cause change. Because work may be done when change occurs, we can describe energy as the ability to do work. Usually measured in Joules.
What is practical unit of energy?
What is practical is a relative question. The unit for electric cars and biology may be Kilo Joules and ev, electron volts.
What is the meaning of CAL in kwh meter?
Calories/cm² (Cal/cm²) is a unit we use to measure this incident energy. You may also hear this energy measured in Joules/CM² but Cal/cm² is ...
What unit is energy measured in today?
I believe it's still calories... ---- It depends what you're measuring.The basic unit of energy in science is the joule.In food science, the amount of energy that a food may release is measured in calories or joules.
How may joules are in 255 calories?
1,067,634.
Why do your battery drain when you try and start your car?
It could be that the battery is not fully charged or that the battery is incapable of holding a full charge, or that the starter is faulty or that you've just been trying to start the engine for a long time and ran the battery down. Understand that a battery is just an electrical storage device. It only STORES electrical power for use NEXT time you want to start the engine. * If the battery is not fully charged (it didn't get enough electrical energy put back last time it was used), it may not have enough electrical energy to start the engine. * If the battery is going bad, it may not have enough electrical energy to start the engine. * If the starter is going bad, it may pull more energy from the battery than it can provide.
