when voltage increases and currents stays the same what happens to wattage?

Power = voltage * current * cos (power factor);
So if voltage increases, and current stays unchanged, power usage will also increase in proportion.
A: Power is a factor of voltage and current therefore the power will increase if one or both are increased

∙ 11y agoIn DC power, Wattage is simply Voltage * Current. In AC, the formula is a bit more convoluted with a couple of more factors, but the principal is the same.
Thus, if the voltage goes up and the current stays the same, then the wattage will increase. The only exception is if the power factor changes while the voltage changes.

What happens if transformer wattage is much less than load wattage?
If the load current is too high, the power lost in the transformer windings will be too high and it will overheat. If the voltage is excessive, the power lost in eddy currents in the magnetic core will be too high and it will overheat.
Wattage needed for 750 milliampre?
That depends on the voltage V. Wattage P = amperage A times voltage V.
How does the lumen output change as wattage increases for an MR16 bulb?
Generally the lumen output of bulbs is proportional to the power used, if the bulbs are operated at their rated voltage.
How do you find the actual wattage of an electrial component?
Wattage= current*voltage*power factor. Wattage=VI Cos(@)
How you determine wattage?
wattage is nothing but power product of current and voltage p=v*i
How do I calculate wattage?
Wattage, you mean power. Power = V * I. V - the voltage and I the current.
Vacuum is 1100 watts how many amps is that?
If running at 110V, that is 10Amps. Wattage = Voltage x Current Current = Wattage / Voltage - Neeraj Sharma
What is the Formula you can use to find the capacity of a laptop battery?
Wattage = Outage Voltage + Outage Wattage
How do you calculate line current?
Devide the wattage by the voltage
Wire size for an electric range?
Wire size is based of the amperage of the device. To answer this question the amperage is needed or the wattage and voltage of the device.
What is the wattage in the circuit?
wattage is voltage and amperage multiplied. example V/A=W or 120v x 20a=2400 watts
How many anps are in 21 kw?
It depends on the voltage; which depends on the country. If you know the voltage, divide the wattage by the voltage, the result is the amperage.
