if the load is capacitance then reactive power is injected in the circuit, as we know that reactive power is directly proportional to the voltage, if there is increase in reactive power automatically voltage at load end of the tranformer is increases
Electronics are used in thermal power plants when the power from the thermal power plants are transferred to a storage source. There, electronics comes in.
The type of power supply being used (AC or DC) should match the power requirements of the device it will be supplying power to.
A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
Power transformers can be used for power transformation. Voltage transformers are not suitable for high power applications.
The energy that allows you to lift a backpack comes from the food that you eat, especially carbohydrates. The energy in carbohydrates is stored in molecules of ATP during the process of aerobic cellular respiration. When you need energy, ATP is broken down into ADP + P + Energy. That energy is used by the cells to do work, including lifting a backpack.
backpack jack
The straps on the front of a backpack are used for securing extra items, such as a jacket or sleeping bag, to the outside of the backpack.
Bungee cords on a backpack are used to secure and hold items like jackets, water bottles, or other gear on the outside of the backpack.
The three lifts squat, bench press, and deadlift are used in powerlifting, a strength competition, in three attempts at their maximum weight.
Ergonomics as applied to backpack is mostly just a buzz word used by a high percentage of "Backpack johnny come latelys' as a sales tool. The application of ergonomics to backpacks increases as the contained weight in the backpack increases. There are some major ergonomic factors articles that break a little light on the subject but fall far short of the overall picture. Example: I have never seen an Internet article that mentions the back sweat factor or the fact that if the ergonomics is good a cross chest strap isn't needed.

Backpack coolers are usually used too keep drinks cool when someone is riding a bike. The Cooler is carried around as a backpack and allows the rider to have access to chilled drinks.
A backpack used for trekking.
I think it means backpack. It is used in another way though and I can't figure it out
pulleys
The work done in lifting the box is given by W = force x distance = 100 N x 10 m = 1000 J. Since power is the rate at which work is done, the power used in lifting the box is P = work / time = 1000 J / 5 sec = 200 Watts.
a backpack or rucksack. :)
