How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
What does chemical energy mean in physics?
chemical energy,Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic. Reactions that require an input of heat to proceed may store some of that energy as chemical energy in newly formed bonds. The chemical energy in food is converted by the body into mechanical energy and heat. The chemical energy in coal is converted into electrical energy at a power plant. The chemical energy in a battery can also supply electrical power by means of electrolysis.
How can the national grid network overcome black-out in a residential area?
channel the electrical energy supply form other substations to that area
Is a light bulb an example of stored energy?
No. A light bulb can only USE energy, it cannot STORE it. Before it can operate it needs to be given a supply of electrical energy and, from that input of energy, it produces outputs of energy in the form of heat and light.
How is the cost of electrical energy consumption computed?
The cost of electrical energy is computed per energy unit. The more energy you use, the more you will be charged. The unit normally used is the kWh (kilowatt-hour), which is equal to 3,600,000 watt-seconds or joules.The cost per kWh is, at least roughly, determined by supply and demand.
What are the purposes of battery?
Batteries are usually used for supply electrical energy to a electrically working device. They have many role in our daily life.
What is the use of a power supply?
power supply is a device that supplies electric power to electrical load
What is the power of a power supply?
power supply is a device that supplies electric power to electrical load
How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
Is ups input or output device?
UPS is Uninterruptable Power Supply. It is neither input not output. It supplies electrical power to a computer when the main electrical supply is interrupted. It does not handle data in any way.
Is a battery considered electricity?
The battery is not electricity. A battery is a device that stores energy in the form of chemical energy. When energy is taken out of the battery, it comes out in the form of electrical energy. And if the battery is rechargable, then energy is put into it also in the form of electrical energy. A2. There is sometimes a confusion, amongst non-technical people when discussing electrical items. A distinction is made between an AC mains operated device and a battery operated device. Calling the mains device 'electric' and the other 'battery'. A battery operated device is also 'electric', The current is DC and the voltage usually a lot lower (and safer) than the domestic supply. So yes. A battery operated device is electric. Batteries do produce electricity.
What is an energy storage device?
The most familiar energy storage device is a battery used for electrical power supply. Energy can also be stored in a flywheel, in a spring (wristwatches, in earlier decades, used to be powered by a mainspring that you had to wind up by hand, rather than by batteries) and various other things.
Does a power supply continue to use energy when its device is unplugged?
no
Do 68 percent of the electrical energy in the US produced by Nuclear Fuel?
No. About 20% of the US electrical energy supply is from nuclear power.
A device in a circuit that uses electrical energy to do work?
This sound like a basic Physics, or Electrical Shop' question ferom a high school student. If you really need an answer post it again or contact me and I'll supply another answer.
What kind of energy does a battery supply?
The type of energy a battery supplies is either electrical of chemical.
Uses of adaptor?
used to connect an electrical device to a mains supply when they have different types of terminals
