How many watts are consumed by a light if 1.2 amperes are measured when 12 voltages are applied?
14.4 watts
Which uses more watts a 100Watt light bulb or a toaster?
That depends entirely on the toaster, but in general, most toasters use over 1,000 watts.
How do you discharge 25 Kvar capacitor in 690Volt system?
This capacitor carries a current of 25,000/690 or 36.2 amps and its impedance (reactance) is 19 ohms. The capacitance is 1/(2.pi.50.19) or 0.000167 Farad, on a 50 Hz system. The time-constant is CR so that if a 20,000 ohm resistor is placed across the capacitor the time-constant is 3.3 seconds. The voltage is reduced by 99% after 5 time-constants or in this case 17 seconds. If the discharge resistor is permanently in circuit it dissipates 690^2 / 20000 or 24 watts.
How much kvar capacitor bank installed for 2000 kva transformer?
It depends on the power factor of the load, but for a load power factor of 0.7 on a 2000 kVA transformer the real power and reactive power are both 1400 kilo (watts and VAR). So a 1400 kVAR capacitor on the load would restore the power factor to 1, allowing 2000 kW to be drawn instead of only 1400 kW.
How many watts is 7 amps?
In general, multiply the (rms) current by the (rms) voltage to get the power. If the voltage to the appliance is 120 Volts, then the power of 4.2 Amps is 504 Watts. If the voltage is 240 Volts, then 1008 Watts. Note: To be technically accurate, you must also multiply the cosine of the phase-angle between current and voltage. For any typical appliance, this is 1 and can be ignored. <<>> There are zero watts in 4.2 amps. Watts = Amps x Volts. Without a voltage stated the wattage can not be calculated.
How many watts does a Sodium Vapor light bulb have?
sixty
What size capacitor you need for a 1000 watts amplifier?
It takes 1 farad for every 1000 watts so u need 2 farads.
How bright is 950 lumens?
220 lumens is equal to a tungsten incandescent light bulb of 15 watts. Halogen lamp 20 watts. Fluorescent lamp 60 watts. LED lamp 60 watts. high pressure sodium vapour lamp 117 watts. Mercury vapour lamp 50 watts or 17.32 candle power
What wattage high pressure sodium bulb to use for hydroponic vegetable growing?
6000 watts should be enough. Good luck!
How much energy does a 1000 wate high pressure sodium lamp use?
400 W HPS bulb: actual wattage pull would be around 440-480 watts when it is on
How many watts is a 500k microfarad rated for?
The wattage of a capacitor, such as a 500k microfarad capacitor, cannot be determined solely from its capacitance value. Wattage is a measure of power, which depends on both voltage and the current flowing through the capacitor. To calculate the power (in watts), you would need to know the voltage across the capacitor and the frequency of the AC signal if applicable, as well as factors like the capacitor's equivalent series resistance (ESR).
What type of night light will last me several years?
It's claimed that LEC or Light Emitting Capacitor nightlights have the longest lifetime.It's not exactly a lightbulb though Limelite claims their product only uses 3 watts per year.
When was Watts Island Light created?
Watts Island Light was created in 1833.
When did light bulbs start using watts?
Light bulbs have always used watts.
What is the highest watt light bulb?
For a standard household incandescent it is 200w. Mogul incandescents can reach 3-500w depending. Halogen tubes typically reach 500w. Sodium-halide , high pressure sodium , Mercury vapor , and Arc lamps can reach into the thousands of watts but are not usually used in a household setting.
How many 40 watt bulbs are equal to a 400 watt high pressure sodium bulb?
In terms of power comsumption, it's simple - 10. 40 watts times 10 give 400 watts. In terms of lighting ability, it's not nearly so simple. Ten dim bulbs don't provide as intense a light source as one bright one. They can be spread out to better light a large area and maybe not have as many shadows as would a single light source, but nowhere will it be very bright, even if the ten dim bulbs are all next to each other. So, the proper answer to your question is, "There is no real 'equivalence' between the two."
Does a 100 watts light bulb have 100 watts or does it use 100 watts when lit?
Use 100 watts
