How many watts of led equals 40 watts of fluorescent?
Watts are a unit of power. So 40 watts of power to an LED are the same as 40 watts of power to a fluorescent. Sometimes LEDs are rated in equivalent watts which is an attempt to relate watts to brightness or lumens. You need to compare lumens and the "temperature" of the bulbs in Kelvin to get the comparison I think you are looking for.
How many LED lights can you put on a 20 amp circuit?
The electrical code states that circuit conductors that are fed by this breaker on a continuous load can only be loaded to 80%. Therefore you can have a load of 1,920 watts on this circuit. Assuming you install 8 watt bulbs you can have 240 on this circuit.
How do you convert amps to amp hours?
volts times amps equals watts, a measure of power. Amps times hours equals amp-hours, a measure of electric charge. Electric charge times voltage is energy. So 120 volts at 10 amps for 4 hours would pass 40 amp-hours of charge, the power would be 1200 watts and the energy would be 4800 watt-hours or 4.8 kilowatt-hours. So volts times amp-hours equals energy in watt-hours.
What does 40 VA mean in a transformer?
In a transformer, 40 VA refers to the apparent power rating of the transformer. VA stands for volt-ampere, which is a unit used to measure apparent power in an electrical circuit. A transformer with a rating of 40 VA can handle a maximum apparent power of 40 volt-amperes, which is the product of the voltage and current it can handle. This rating is important for determining the capacity and suitability of the transformer for specific applications.
What gauge wire for a jacuzzi with a 40 foot run?
Depends on the amperage of the Jacuzzi and if it is 120 or 240 volts.
