How do you calculate ampere given 250v AC 60W?
Divide the watts by the voltage to get current (amps). 60W / 250V = about 1/4 Amp.
How do you convert volts to mva?
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')!
How do you work out ampere hour?
An ampere-hour is one ampere for one hour.A ampere is one coulomb per second, so an ampere-hour is a transfer of charge of 3600 coulombs.See the discussion page.
How long will a battery 12 ampere-hour rating supply 144 watt load?
An ampere-hour rating is a relatavistic indication of how long a battery can supply a specific current.It is not possible to determine the run time when you only gave watts, but watts are volts times amps, and you did not supply the volts.
What is a volt-ampere the product of?
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.
How many watts need for seven ampere's and 120 volt's?
770 watts.
How do you compute for the watts?
Voltage x current
How do you calculate ampere given 250v AC 60W?
Divide the watts by the voltage to get current (amps). 60W / 250V = about 1/4 Amp.
How can you compute the number of watts?
watts = volts x amps x power factor
How many watts in 1 ampere 230 volt?
Watts = Amps X Volts Grab your calculator!
How much watts in one ampere?
Since the equation for watts is: Volts * Amps = Watts that would mean 12 Volts * 1 Amp = 12 Watts
How many watts equal one ampere?
One ampere is equal to one watt in a system with a voltage of one volt. This relationship stems from Ohm's Law (P = V x I), where power (P) in watts is equal to voltage (V) in volts multiplied by current (I) in amperes.
How do you convert volts to mva?

How may watts in one ampere?
Watts is a unit of power, whereas Amperes is a unit of current. They're related though, along with Voltage, Resistance etc. But they're not the same thing, so to answer your question: There are no watts in an ampere! Power (W) = Voltage (V) x Current (I)
How do you compute the 2000 watts in 220 volt to how many amps?
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
Is there 1200 watts in 12 volts?
If the 12V source can deliver 100 Ampere, then yes. If it can't, then no. (remember watts / volts = amps)
Can it may be a combination of 10 volts and 10000 ampere?
Sure, but of course this will be 100,000 watts.
