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.
How many watts in 40 amps?
I t depends. Watts = Amps times volts. 40 amps x 120 volts =4800 watts or 40 Amps x 12 volts = 480 watts.
How many amps are in 40 watts?
That depends on circuit voltage. 1 watt is equal to 1 volt times 1 amp.
What is in watts of a bulbs that operates at 40 voltage with a current of 0.5?
Watts equal volts times amps, which is 40 x 0.5 or 20 watts.
4 volts is a many watts?
4 volts and how many amps? Watts = amps x volts. It depends on the amount of current (in Amps) flowing at 4 Volts... See Ohms Law: Watts = Volts x Amps If you have 2 Amps flowing at 4 Volts you are dissipating/consuming 8 Watts. If you have 10 Amps flowing at 4 Volts you are dissipating/consuming 40 Watts.
25 amps is how many kw?
Amps is a measurement of current. Watts (or kilowatts) is a measure of power. To get the power from the current, you have to know the electrical potential or volts used to produce the current. Amps × Volts = Watts (or Current × Electrical Potential = Power). Incidentally, a kilowatt is 1000 watts, so you'll have to divide your answer by 1000. e.g. if your volts is 40, then 25 amps × 40 volts = 1000 watts. 1000 watts (divided by 1000) is 1kw or kilowatt.
How many watts make a volt?
Watts are a unit of power and Volts are a unit of electric potential, so they cannot be directly compared. However, Watts and Volts can be related byWatts = Volts * AmperesorWatts = (Volts^2) / Ohmswhere Amperes are a unit of current and Ohms are a unit of resistance. So, for example, if a lightbulb draws .333 Amps of current at 120 Volts, it is a 40 Watt bulb. (.333 A * 120 V = 40 W)
How do you work out how many amps a forty watt bulb uses?
To calculate the amperage of a 40-watt bulb, you need to use the formula: Amps = Watts / Volts. If the bulb operates at 120 volts (standard for US households), the amperage will be 0.33 amps (40 watts / 120 volts).
Can you use 2 40-watt florecscent bulbs in a fixture rated for 67 watts120 volts?
No Because 40+40 is 80 watts.
What is the resistance of a 40 watt bulb?
To calculate the resistance of a 40 watt bulb, you need to know the voltage it operates at. You can use the formula P = V^2 / R, where P is power (40 watts) and V is voltage. Without voltage information, the resistance cannot be determined.
A low amps power source is converted into volts and powers a 60 watt light bulb what is left?
40 watts
How many watts is 40va?
40 VA is the apparent power of the load. It is simply the applied voltage multiplied by the resulting current in amperes. Given the VA and the Volts merely divide the VA by the volts to get I=VA/A = 40VA/24V= 1.667 Amperes rms. Andy B
When you applied 230 volt and current of choke is .43 amp then according to power formula the value is 99.82 watt while on tube light it is marked as 40 watt how it can be possible?
In an AC system the power is often less than the volts times the amps. The full formula is watts = volts times amps times power-factor. Some bulbs have a power-factor as low as 0.5.
