Current is common throughout the world. The current is based on what the load draws. The equation you are looking for is Amps = Watts/Volts. Other equations for amperage are Amps = Sq root of Watts/Ohms and Amps = Volts/Ohms. So as you can see the amperage is dependant upon the the value of voltage, wattage and resistance.
The amp draw on this voltage will depend on what is connected to it. Will be no amp load until a load is applied to it.
Since power = current x voltage, you would divide the power (watts) by the voltage. The answer would be 1/10 amps or .10 amps.
current is the other factor. power (wattage) is the product of current (amps) and voltage
Ohm's law: Volts = amps times ohms In the case of a 4 ohm resistor with 1.5 amps of current, the voltage is 6 volts.
voltage is measured in terms of volts ; current is measured in terms of amps.........................................
You would also need to know the current in amps. The formula you need is this: P = I V Power (in watts) = current (in amps) x voltage (in volts)
You just need the voltage and the current. Watts = Amps x Volts.
current = power/ voltage current = 3700/ 240 = 15.4 amps
If voltage is given as RMS voltage (which it normally is), simply multiply the number of volts by the RMS current (as number of amps), and then divide by one thousand. Power (in kW)=Voltage (RMS volts) * Current (RMS amps) / 1000 (watts/kW)
60 Ohms
Watts is voltage (in volts) x current (in amps)
Since power is voltage times amperes, in order to double the power while voltage remains the same, you must double the current - 4 amps in this case.
Electrical power = current x voltage Current is in amps
