Because they are different characteristics.
If you'd compare electricity to water, Volts would be the pressure, and Amps would be the flow.
So you can have high pressure but little flow - like a water pistol. Or you can have high flow and little pressure - like upending a bucket.
12 va These are two different entities. Its like asking how much water will flow with pressure. With the following formula W = Amps x Volts you can see the relationship they have with each other, the end product resulting in Watts.
== == Volts are a measure of electrical "pressure" differential.
Countries use either 220 volts or 110 volts based on historical decisions, grid infrastructure, and safety regulations. North America and some parts of Japan use 110 volts, while Europe, Asia, Africa, and Australia use 220 volts. Each system has its benefits and challenges, but the choice typically depends on what was established when electricity infrastructure was first developed.
Voltage or electric potential tension measured in units of electric potential: volts, or joules per coulomb) is the electric energy charge difference of electric potential energy transported between two points.
No. Amperage is the current flowing down the conductor as voltage is a constant (relatively). As an example- a 120 volt light bulb is of course 120 volts but if it is 60 watts then it will draw .5 amps. a 100 watt bulb will draw around .8 ampsDifferent things.
The watt is the unit of power. For electricity, watts = volts x amps.
Amps measure the current flowing in a circuit, watts measure power output, and volts measure voltage difference. In an electrical system, volts x amps = watts, so they are related but measure different aspects of electricity. Volts represent the force pushing electrical current, while amps indicate the rate of flow, and watts show the total power consumed or produced.

Amps (amperes) measure current flow in a circuit, showing how much electricity is flowing. Watts measure power, representing the rate at which energy is consumed or produced. In simple terms, amps indicate the amount of electricity flowing, while watts indicate how much work or energy is being used.
It's watts divided by volts equals amps. Example: 1200 watts at 120 volts is 10 amps. To get the watts if you know the amps, multiply the amps times the volts. 10 amps at 120 volts is 1200 watts.
Amperes measure the rate of flow of electricity in a conductor Volts measure electrical pressure Watts measure the amount of energy or work that can be done by Amperes and Volts Relationship: Work = Pressure x Flow or Watts = Volts x Amperes When you know two variables you can calculate the other Formulas - This formula referred to as the West Virginia Formula (W - VA)Watts = Volts x Amps Volts = Watts / Amps Amps - Watts / Volts Refer to link below for more information
The watt or kilowatt (1000 watts) for power, volts for potential difference, amps for current
Watts = current x volts, so you have to multiply Kw value by 1000 to get watts, then divide by the applied voltage. examples. 2Kw kettle (U.S) current = 2 x1000 divided by 120, or 16.7 amps 2Kw kettle (UK) current = 2 x1000 divided by 240 or 8.35 amps 100 watt car amplifier current = 100 divided by 12 volts = 8.5amps
Pressure
Volts and amps measure two different things. Volts are used to measure potential difference. Amperes (amps for short) are used to measure current. Compare it to a garden hosepipe: Voltage corresponds to the pressure of the water, current measures how fast the water flows. 2000 millivolts equals two volts. For comparison, a single AA cell gives 1.5 volts. 1000 amps is several times the current used by the average household. A regular AA cell can provide, at maximum, about half an amp.
Milli amps is a measure of current whilst watt is a measure of power. The missing element is voltage as the formula is:- Power = Voltage * Amps ie power in Watts is the product of Volts (in Volts) times Amps (in Amps)
