You cannot increase voltage by adding amps.
250 watts divided by 12 volts = amps or around 20 amps
To convert watts to amps, you need to divide the wattage by the voltage. In this case, 9.6VA divided by 12V equals 0.8 amps. So, 12 volt 9.6VA is equivalent to 0.8 amps.
The power (in watts) can be calculated by multiplying the current (in amps) by the voltage (in volts). In this case, 10 amps at 12 volts would result in 120 watts of power (10A * 12V = 120W).
The ohms will usually stay the same unless the Amps are somehow effecting the temperature. The Amps will always change with the volts.
There is no formula needed, they are the same thing, just two different wordings.
To answer this question a voltage value must be stated. Divide the voltage into 50 KVA and your answer will be in amps.
( 746 watts = 1horse power ) On 12 volt systems ( volts X amps ) =( watts )12volts X 6.5amps = 78watts. Now ( watts / 746watts ) 78watts / 746watts =0.105hp
The maximum current rating for the circuit breaker needed for a device that operates at 20 amps is 25 amps.
6volts 2amps for 6 volt battery, and 12 volts 6amps for a 12 volt battery. Don't charge a 6 volt battery on the 12 volt setting or it will explode!!!!!!!!! you're ok going the other way though.
The guage of wire for 20 amps is #12 copper.
3 things Volts, ohms, and amps
Mpre information is needed to specify the question more accurately.
