What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?

When connected to a 110-volt supply, the 60-watt 220-volt lamp will consume power that is calculated using the formula P = V^2 / R, where P is power, V is voltage, and R is resistance. Since the resistance of the lamp remains constant, the power consumption would be (110^2 / 220) = 55 watts. Thus, the lamp would consume 55 watts of power when connected across a 110-volt supply.


What is brighter 60 Watt 110 volt or 60 Watt 220 volt?

If the voltage supplied to the lamps is its operating voltage both lamps will have relatively the same output in brightness. If the 60 watt 110 volt lamp is used on a 220 volt supply, it will glow very brightly and then the lamp's filament will burn open. If the 60 watt 220 volt lamp is used on a 110 volt supply, the lamp will glow at half brightness, but it will last for a very long time before the filament burns open.


How much power does a 250 watt hps light use an hour?

A 250 watt HPS light will use 250 watts of power per hour. This means it will consume 0.25 kilowatt-hours (kWh) of electricity in one hour of operation.


What is the relationship between a volt an amp and a watt?

A volt is the unit of electric potential, an amp is the unit of electric current, and a watt is the unit of power. The relationship between them is described by the equation: Power (in watts) = Voltage (in volts) x Current (in amps).


What wire size is used for 100 watt 12 volt lamp?

For a 100 watt 12 volt lamp, you should use a wire gauge size of at least 18 AWG to ensure it can handle the current without overheating. It's always best to refer to the manufacturer's recommendations for the specific lamp you are using.

How many amps is 400 watt in 240 volt?

calculation for Watts is = volts X amps P=IE P= Power(WATTS) I = Current(AMPS) and E = Voltage(VOLTS). So: I = P/E and E = P/I therefore: 1 watt = 1 ampere x 1 volt If you havea 240 volt lamp that is drawing .5 amp then it is using 120 Watts

How many watts per hour to equal 1000 btu's?

The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.
