AC power is electricially, a value that is expressed in watts and voltage is the electromotive force that combined with amps, makes up the formula to find watts. Watts is the product of Amps x Volts. W = amps x volts.

In a power station where dc is actually converted to ac while distribution?
The generated voltage in a power station is AC voltage, not DC. So, it is never converted to AC, because it is already AC.
Is the power line voltage available in your homes a DC or an AC voltage?
We deliver power on the power grid as an AC voltage. That's alternating current, and that's what is available in your home.
Does the neon power supply for those beer signs in bars output high voltage AC or DC?
High Voltage AC.
What determines power?
Power = Current * Voltage * Power FactorAbove expression can further be explore as :1. For DC CircuitsPower = Current * Voltage2. For Single Phase AC CircuitPower = Current * Voltage * Power Factor3. For Three Phase AC CircuitPower = Line Current * Line Voltage * Power Factor
What is the household ac electrical power mains voltage in Italy?
The voltage is 230volts and this is the norm in Europe.
Is the RMS value of the power output of a device running on a certain AC voltage equivalent to the power output of a similar device if it was running on the same voltage but it was DC instead of AC?
Yes.
Does centre tap transformer convert ac voltage to ac voltage?
Yes. Transformers convert power by stepping up or down voltage. It doesn't matter what tap configuration they have.
Is tranformer used to increase or decrease AC voltage?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.
What factors determine power?
Power = Current * Voltage * Power FactorAbove expression can further be explore as :1. For DC CircuitsPower = Current * Voltage2. For Single Phase AC CircuitPower = Current * Voltage * Power Factor3. For Three Phase AC CircuitPower = Line Current * Line Voltage * Power Factor
How is power and voltage related?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
What is a backlight inverter?
a form of low voltage DC to high voltage AC power conversion circuit.
Which conditions refers to a reduced voltage levels of AC power that lasts for a period of time?
Reduced voltage levels of AC power that lasts for a period of time is known as a brownout.
