Current (amps) = power (watts) / voltage
= 100/240
= 0.42 amps
A 22VA transformer has a power rating of 22 watts. VA (volt-ampere) is a unit used to measure the apparent power in an electrical circuit.
One ampere is equal to one watt in a system with a voltage of one volt. This relationship is defined by Ohm's Law, which states that power (in watts) is equal to current (in amperes) multiplied by voltage (in volts).
The wattage of the circuit presuming that the circuit voltage is 120 volts. 20 x 120 = 2400 watts. Circuit loading on a continuous load is 80% so 2400 watts x .8 = 1920 watts
Batteries are generally not listed as having watts. And there are a couple of different ampere ratings. But if you're running something needing 12W of a 12V battery it's pulling 1A out of the battery at the moment.
There are 1,000 watts (W) in a kilowatt (kW) and 1,000 volt-amps (VA) in a kilovolt-ampere (kVA). Therefore, 1 kVA is equal to 1 kW.
770 watts.
Watts = Amps X Volts Grab your calculator!
The same number as 250 oranges is apples. A watt is a volt times an ampere.
ohm is used to measure resistance of electric current. Ampere is used to measure electric current. volt is used to measure voltage.

About as much as 15 typical (60watt each) light bulbs together. Or expressed in horsepower: about 1.2Hp Mains volts and ampere: 230 volt at 3.91 ampere = 900watt 110 volt at 8.18 ampere = 900watt
Watts (or kilowatts) and amperes are used to measure different things. Watts is a unit of power; ampere is a unit of current. The relationship (for direct current) is: watt = ampere x volt For AC, the relationship is a bit more complicated: watt = ampere x volt x power factor However, the power factor is often close to one.
One ampere is equal to one watt in a system with a voltage of one volt. This relationship is defined by Ohm's Law, which states that power (in watts) is equal to current (in amperes) multiplied by voltage (in volts).
Do you mean 'megavolt ampere' (MV.A) or 'millivolt ampere' (mV.A)? By using the incorrect symbol ('mva'), this is not clear.To determine the apparent power, in volt amperes, you divide the true power, in watts, by the power factor of the load. One volt ampere is one-millionth of a megavolt ampere ('MV.A' -not 'mva') -assuming you don't mean 'millivolt ampere' ('mV.A')!
A volt - ampere is the unit for the product of voltage and current. This is power. Power = voltage x current. The unit of power is more usually called the watt. Volts x amps = watts.
There are no 'volt amperes' in a horsepower. A volt ampere is used to measure 'apparent power', which is an electrical quantity. In other words, you are trying to compare apples with Oranges. You can convert watts to horsepower, because they both measure the same thing: power.
The battery life (assuming it is a primary cell) is determined by the Ampere-hour drawn from it. You cannot connect a 3.5V bulb directly to a 9V battery. The bulb will fuse.
