Wattage = voltage times amperage. That's for DC.
For AC there is a power factor PF = cos phi you have do multiply with.

There are lots of different ways of calculating power; it depends entirely on what information you have to start with. In basic terms, power is simply work divided by time.
To calculate the watts in 16kV, you would need to know the current flowing through the circuit. The formula to calculate watts is Watts = Volts x Amps. Without the value of current (Amps), we cannot determine the watts.

To calculate the number of watts when given volts, you also need to know the current (in amps) flowing through the circuit. The formula for power (in watts) is P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps. Without knowing the current, we cannot determine the number of watts from just volts.
You can determine the amps of any power consuming source by dividing the watts by the volts. Example: If the bulb is 60 watts and your volts are 120, then 60/120 = .5 amps. Or you could use an amp probe.
To calculate the power in watts, you will also need to know the current in amperes. The formula to calculate power is P (watts) = V (volts) x I (amperes). If you only have the voltage (30 volts) and not the current, you cannot determine the power in watts.

The equation is quite simple. Multiply the number of lights on the system by their wattage to determine the system wattage.

The formula for power (in watts) is P = V x I, where P is power in watts, V is voltage in volts, and I is current in amps. Without knowing the current, we cannot determine the number of watts from just volts.
To calculate watts in cycling, you multiply your current power output (in watts) by your pedaling cadence (in revolutions per minute). This formula helps determine the amount of energy you are generating while cycling.
The power of lightbulbs is measured in watts. This measurement indicates how much energy the lightbulb consumes and helps determine its brightness.
You can determine the amps of any power consuming source by dividing the watts by the volts. Example: If the bulb is 60 watts and your volts are 120, then 60/120 = .5 amps. Or you could use an amp probe.
To calculate the power in watts, you will also need to know the current in amperes. The formula to calculate power is P (watts) = V (volts) x I (amperes). If you only have the voltage (30 volts) and not the current, you cannot determine the power in watts.
To calculate the number of watts in 0.1A, you need to know the voltage of the circuit. The formula for power is P = V x I, where P is power in watts, V is voltage in volts, and I is current in amperes. Without knowing the voltage, it is not possible to determine the power in watts.
To calculate the power in watts, you need both the voltage and current. Without knowing the current, it's not possible to determine the wattage just from the voltage provided (95VDC).
To calculate the watts from amps, you need to know the voltage of the circuit. The formula to calculate watts is: Watts = Amps x Volts. So, without knowing the voltage in the circuit, it is not possible to accurately determine the wattage from just knowing the amperage.
There are zero watts in 240 volts. To determine watts, an amperage or a resistance must be supplied. W = Amps x Volts, W = Amps (squared) x Resistance (in Ohms), or W = Voltage (squared)/Resistance.
