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


What happens to a battery when you move it closer to a circuit?

When you move a battery closer to a circuit, it can create a potential difference that may influence the circuit's electrical behavior. If the circuit is designed to connect to the battery, bringing it closer can facilitate a connection, allowing current to flow and powering the circuit. However, if the circuit is not designed to connect to the battery, there may be no effect. The battery's proximity alone doesn't change its stored energy; it simply affects the potential for electrical interaction.


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.

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.


Is more joules better than less joules?

It depends on the context. In some cases, more joules can mean more energy or power, which may be better. But in other cases, less joules may indicate greater efficiency or less waste, which could be preferable.

A battery is not a type of energy. It may CONTAIN chemical energy, if it is loaded.


What is heat energy measured in?

Heat energy is most commonly measured in units of calories or joules.


What happens to the energy in a battery when the battery is all used up?

When a battery is fully discharged, the chemical energy stored inside it is converted into electrical energy, which powers devices until the battery can no longer produce a usable voltage. Once depleted, the battery's chemical reactions can no longer occur efficiently, leading to a loss of energy output. The energy that was once available is no longer accessible, and the battery may require recharging or replacement to restore its energy capacity.


What would be a typical joules rating for a surge suppressor designed for home use?

Destructive surges can be hundreds of thousands of joules. A protector rated for hundreds of joules does not claim to protect from the other and typically destructive surge. In fact, a 250 joule surge will simply be converted by electronics into low voltage DC to safely power its semiconductors. A destructive surge may be 20,000 amps. So a minimal 'whole house' protector for all homes should be at least 50,000 amps. Any protector that fails on a surge did not provide effective protection. And was a potential house fire.


Does a cell phone need a battery to function?

Yes, a cell phone requires a battery to function, as it provides the necessary power for the device to operate. The battery supplies energy to the phone's components, including the screen, processor, and communication systems. Without a battery, a cell phone would not be able to turn on or perform any tasks. However, when connected to a power source, some phones may operate without a battery, but this is not typical for standard use.


What are the energy transformations that take place in a battery powered car?

In a battery-powered car, chemical energy stored in the battery is transformed into electrical energy when the battery discharges. This electrical energy powers the electric motor, which then converts it into mechanical energy to drive the wheels. Additionally, some energy may be lost as heat during these transformations, particularly in the motor and electronic components, but the primary transformation is from chemical to electrical to mechanical energy.
