If you know the voltage (volts) and current (amperes), you can convert to power (watts), but power is not energy. Power is the rate of energy (joules per second). You need to know the time as well to determine energy.
Since the ampere is the SI unit for current, and the volt is the SI unit for potential difference, we are looking at two completely different quantities. So you cannot convert one to the other.
Amperes are a measure of current.
Volts are a measure of electrical pressure (voltage)
To convert one to the other you need to take the resistance to flow into account.
current (in amperes) =...
In a DC circuit watts and volt-amperes are the same, as 1W = 1V x 1A, but in an AC circuit they have different meanings.Volt-amperes (VA) are used as a measurement of "apparent power" delivered to a...
1 horsepower = 745.7 watts. A kilovoltampere must be a kilowatt, so 1 horsepower = 0.7457 kilowatts Further Answer A kilovoltampere (kVA) is only equal to a kilowatt (kW) for a purely resistive load...
