What is the meaning of term KV in electricity? how is it related with watts?

Question

if the air conditioner mentions 1 ton, how much load will it take?

Answer 1

KV means kilovolt or 1000volt.

Power consumption in Wattage= Current in Ampere x Voltage in volt

An 1ton capacity air conditioner is rated to deliver 12000BTu/Hr or 3000kCal/Hr. In other word it can extract heat at the rate 12000BTu/hr or 3000kCal/hr. The power consumption of an 1 ton AC is around 1400-1600 Watts. That means if you run an 1 ton AC for 1 hour it will consume 1.4-1.6 units.

Answer 2

KV means Kilo-volts, or 1000 volts. Amperes (Amps) is the force necessary to move the voltage through the watts (or resistance) required to power any devices on the circuit. The formula is knows as Ohms law.

Ohms Law:

I = V/R

Where I is the current, V is the potential difference, and R is a constant called the resistance. The potential difference is also known as the voltage drop, and is sometimes denoted by E or U instead of V.

The amount of resistance that a device has decreases amps as long as watts and volts remain fixed. Watts are normally seen in the form of heat or light. The lower the resistance (watts), the hotter or brighter something might get (like a light-bulb). Furthermore, when you have low resistance, electricity can flow freely, so you amperage (speed of flow) would increase. Things that don't conduct electricity very efficiently, like the human body, have "high resistance". When you apply electricity to the human body, the force to move the electricity through the body has to increase, causing a slower flow of electricity or lower amps. However, the increased resistance causes heat and light which can cause sever injuries.

To determine how many amps your circuit will require, simply add the total serial watts of every device together and divide that by your total voltage. For example, if you have a blow dryer that says "1500 watts" on the label, a microwave that says "900 watts", and a toaster that says "2400 watts", your total max wattage would be 4800 watts or 4.8 KW (Kilo-watts). To calculate your total max amperage, divide that amount by the applied voltage. In this case, that would 110 volts... so...

110/4800 = .023 Amps

Granted, this is the max amount of amps this circuit would use and would only be this high when all devices were working at the maximum output at the same time.

Hope this helps!

Answer 3

Kv means kilo volts
Kv is simply a measure of how many revs per minute the motor will run per volt of input. If two motors have the same watts rating but different kv then, all else being equal, the one with the higher kv will rev faster than the one with the low kv, and will also require a smaller propellor (or a gearbox and a larger prop) than the motor with the low kv.

Of course, volts and amps also come into consideration because more volts on the low kv motor could make it run the same speed as a higher kv motor; but you'd then have to control the amps by propping down to keep the watts within the motor's spec. (watts = amps x volts).

Answer 5

KV is Kilo ( One Thousand ) Volt : 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,

The watt (symbol: W) is the SI derived unit of power, equal to one joule per second. A human climbing a flight of stairs is doing work at the rate of about 200 watts; a highly trained athlete can work at up to approximately 2000 watts for brief periods. An automobile engine produces 25 000 watts (approximately 30 horsepower) while cruising. A typical household incandescent light bulb uses 40 to 100 watts.

Answer 7

KV in electricity means Kilo Volts. It is used to express the value of potential difference for which the fundamental unit is "volts". Kilo in metric units means 1000. Thus, Kilovolts is equal to 1000 volts. It is easier to express, say, 110,000 volts as 110 KV.
Voltage (KV) is not directly related to Watts, but voltage (KV) is used for calculating Watts which is electric energy.
Watts = Voltage (Volts) x Current (Amperes) x power factor (cos phi)
If you use KV for voltage in the above formula, then the power is expressed as Kilo Watts (KW). To express this in watts, you have to multiply the KW by 1000.

Answer 8

Specifies the amount of electric force carried through a high voltage transmission line. In the United States, the standard voltage for use in the home is 120 volts. For long transmission purposes, the voltages go as high as 230,000 volts, or even 1,000,000 volts. Sometimes these high voltages are expressed in kilovolts, a kilovolt being equal to 1,000 volts. A 230,000 volt line would be called a 230 kilovolt line.

An A/C's tonnage, though, is different...:

Heat pumps and air conditioners are generally sized in tons. Typical sizes for single family residences are between two and five tons. Each ton equals 12,000 Btuh. It is important to note that actual capacity is not constant and will change based on outdoor or indoor temperatures. The published capacity rating of air conditioners and heat pumps is based on performance at the ARI standard temperature levels of 95 F outside, 80 F inside.
