Need to know the wattage to work out the amperage
You need to know amps to answer this... Amps x Volts=watts
9.6va (or watts) divided by 12Volts = 0.8 amps
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
To determine the amperage required by a 12-volt audio radio, you would need to know the power consumption of the radio in watts. You can then use the formula: Amps = Watts / Volts to calculate the amperage.
Since watts and volt-amps are different units of power, you cannot directly convert watts to volt-amps without considering the power factor of the load. In an ideal resistive circuit, 100 watts would be equivalent to 100 volt-amps. However, in practical applications with reactive components, the relationship between watts and volt-amps can vary.
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
Depends on the battery. It is listed on the battery as Cold Cranking Amps (CCA).

The heater should have a wattage rating (very few list amps). Calculate the amps using the wattage and voltage. Amps = Watts/Volts(480).

9.6va (or watts) divided by 12Volts = 0.8 amps
2.083 amps
62.5 amps
watts = volts * amps--> Amps = watts/ volts therefore; 2000/220= 9.09 amps
at 240/50 volt itequates to 4amp
55/12=4.6
