what is horse power and its relation to kilowatt, the difference between watt , volt and ampere.?

Answer 1

Power is the measure of work/energy per unit of time.

Work is calculated by the amount of force times the distance the object is moved.

In English units, one unit for power is the horsepower.

One horsepower is the amount of power required to lift 33,000 pounds a distance of one foot in one minute and is related to experiments performed with horses lifting weights from a mine shaft.
So, 1 hp = 33000 lb-ft/min

The SI unit of power is the Watt. One horsepower is equal to 746 W.

A volt is measure of electric potential.

An ampere is a measure for current.

You can determine power from the voltage and current. The formulas differ based on the type of power (AC, DC, 3-phase, etc.)

Answer 2

Picture electricity as water. Volts are the water's pressure. Amps are the water's volume. Watts are the water's power or ability to do something like put out a fire using its volts and amps. Like a water hose with an adjustable nozzle, when you make the nozzle smaller, the water comes out with more pressure (volts). When you make the nozzle bigger, the water comes out with more volume (amps). Electricity is the same. High voltage will arc through the air but unless it has some current too, it is harmless like static electricity. High current will melt a wire but without some voltage it's harmless, like your car battery. The formula for figuring power is P (in watts) = Volts X Amps. A 12 volt battery that puts out 5 amps can make 60 watts of power. Take the battery voltage up to 24 volts and you can get 120 watts of power. That's why portable drills with higher voltage batteries can make more power.

Answer 3

Horsepower (one word) and kilowatts are both units of power--the ability to perform a certain amount of work in a unit of time.

One horsepower is equal to 0.746 watts (approximately)

Not that electric motors and generators are not 100 percent efficient so a 1 HP motor takes more than 746 watts to run. By the same token, more than 1 HP has to drive a generator that produces 746 watts.

Answer 4

The horsepower (hp) is the name of several non-metric units of power. In scientific discourse the term "horsepower" is rarely used due to the various definitions and the existence of an SI unit for power, the watt (W). However, the idea of horsepower persists as a legacy term in many languages, particularly in the automotive industry for listing the maximum rate of power application of internal-combustion engines.

Watt :
One watt is one joule of energy per second.
1 W = 1 J/s = 1 newton meter per second = 1 kg·m2·s−3

Volt :
The volt (symbol: V) is the SI derived unit of electric potential difference or electromotive force. It is named in honor of the Italian physicist Alessandro Volta (1745–1827), who invented the voltaic pile, the first chemical battery
It can also be defined as
The volt is defined as the potential difference across a conductor when a current of one ampere dissipates one watt of power. Hence, it is the base SI representation m2 · kg · s-3 · A-1, which can be equally represented as one joule of energy per coulomb of charge, J/C.

Ampere :
The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in vacuum, would produce between these conductors a force equal to 2×10–7 newton per metre of length.
Electric current is the time rate of change or displacement of electric charge. One ampere represents the rate of 1 coulomb of charge per second.

Answer 5

1 h.p=746watt=0.746k watt
watt is unite of power.
volt is unite of potintial difference.
amperis unite of current.
