What is rating of 1500 kva diesel engine in kw?
Diesel engines are always rated in watts (or horsepower in North America), never in volt amperes which is the unit of apparent power and does not apply to non-electrical machines.However, if you are referring to a diesel-driven generator, then that generator's rated output is indeed measured in volt amperes. The power delivered, in watts, depends on the power factor of the load -e.g. if the load is purely resistive, then the number of watts will be, to all intents and purposes, numerically equal to the volt amperes. For inductive loads (e.g. a motor), then the watts will always be lower than the volt amperes -how much lower, depends on the load's power factor.
How many watts is 60va eqal to?
The relationship between volt-amperes (VA) and watts (W) depends on the power factor of the system. For purely resistive loads, 60 VA is equal to 60 watts. However, if the load has a power factor less than 1 (common in inductive loads), the actual wattage will be less than 60 watts. To convert VA to watts, you can use the formula: Watts = VA × Power Factor.
Can 80 watts power a 12 volt for 16 hours day?
You are confusing the units.If 80 watts can power a device for a second, the same 80 watts can power the same device for a year - assuming the generator, or whatever produces the power, continues working. A watt is a unit of power (energy / time), not a unit of energy. Thus, since you are using units of power, the 16 hours are completely irrelevant to the problem.Nor can you directly compare watts and volts. The relationship is: power = voltage x current. In SI units: watts = volts x amperes. If a device uses less than or equal to 80 watts, your 80 watts will be enough; otherwise they won't. If the specifications of an electrical device only specify volts and amperes, multiply them to get the watts required.
Can you use 20 watts or 30 watts in a fuse?
No, watts are a measure of power while fuses are rated in amperes (amps). To determine the fuse rating, you need to calculate the current in amps by dividing the power in watts by the voltage. Then, choose a fuse that is rated equal to or slightly higher than the calculated current in amps.
True power divided by apparent power?
Real Power: The actual power in Watts or K-Watts in AC or DC Circuits Apparent power: The Power in Inductive or Capacitive Circuits have Phase Lag & Lead measured in Volt Amperes VA or Kilo Volt Amperes KVA
What is 200 WV in volts?
200 WV (watts-volt) is a unit that typically refers to power rather than voltage. To convert watts to volts, you need to know the current (in amperes) flowing through the circuit, as voltage (V) is calculated using the formula V = P/I, where P is power in watts and I is current in amperes. Therefore, without knowing the current, you cannot directly convert 200 WV to volts.
What is the formula to convert amperes from 440V to 460V?
For the same power - Watts - you need to run twice as many amps at 220V than at 440V. For the same load, it'll pull half the amps at 220V than it did on 440V
Why doesn't the amps x volts on a compact fluorescent bulb equal watts?
In a.c. circuits, the product of voltage and current is called 'apparent power', and is expressed in volt amperes. If you want to know the 'true power' of a load, you must multiply its apparent power by the power factor of the load. This is the cosine of the angle by which the load current is (in this case) lagging the supply voltage. Fluorescent lamps have a relatively-low power factor, so the numerical value of the lamp's true power (in watts) will always be somewhat lower than its apparent power (in volt amperes).
How many watts are in 13 amps?
Excellent question. That depends on the voltage, for 120 VAC, the answer is 156 watts. PIE, Power (in watts) = current (amps) X Voltage . For 12 VDC, 15.6 watts. An interesting asside, if you ohms check a 120 watt (should draw 1 amp) incandesent light bulb, it will read much less than you would expect (120 ohms). Turns out, the filament at room temp is much more conductive.
What is the electrical power of light bulbs what is it measued in?
Electrical power of a bulb is real power used by the bulb. It is measured in Watts. In general, the higher the bulb watt rating, the more lumens it will produce. This is not always the case, since some bulbs are more efficient than others at turning electrical energy into light (ie some bulbs produce more heat, an unwanted byproduct, than others). Real electrical power is always measured in watts. Total power (real and reactive) is measured in volt amperes, which is a vector summation of real power plus reactive power. Power times a time it is used is measured in Joules, or watt seconds.
What is 60 watts per channel on a receiver?
about 15 watts actual power but actually more than enogh to wake up the neighbors.
How much power can a device use in sleep mode if it complies with the Green standards?
No more than 30 watts of power
