because the generator generate apparent power in kilos and it is written as ( kilo volt ampere OR KVA) it is the combination of active and reactive powers where active will be used by the consumers and the reactive will come back to the generator.
What crrent does a 203-ohm resistor draw from a 115 V power supply?
Ohm's law: current equals voltage divided by resistance, so a 203 ohm resistor would draw 0.57 amperes from a 115 volt power supply.
Which conductor size has the largest diameter?
The largest conductor listed in the National Electrical Code is a 2000 kcmil.
What are the specs for the Canon PC430 copier?
Some of the specs for the Canon PC430 include a min media size of 4.13 in x 5.85 in and a max media size of 8.5 in x 14 in, the power of AC 120 V (60 HZ) and a 1 year warranty.
Kva demand execess charges from msedcl for indistrial category?
Yes, the KVA can demand for excess charges from msedcl for the industrial category.
No. Transformers remain energised permanently and are only disconnected for maintenance. If the company were to shut off the transformer, then you would lose the electricity supply to your property. An energised transformer normally hums, which is usually an indication that it is energised, however you should ALWAYS assume that a transformer is energised and never interfere with it.
Dear All, Shobhit University, Meerut is well known for its quality teaching. The university is established under section 3 of UGC Act 1956 and is fully recognized. Not only BTech but also other academic programs of the University like MTech, MBA, MPharm, MCA, MPhil and PhD are very popular among the students. Best wishes
You first must determine what wattage each computer consumes. You then need to figure out what your electrical rate is ... the charge per kilowatt hour.
On some motor nameplates you may see 120/208-240. These are not true tri-voltage motors. They are dual voltage motors with a leniency on the 240 volt range to be derated to run on 208 volts. At this voltage the current drops and you don't get the full horse power rating of the motor. To answer your question I have never seen one that would do true three voltages like 120/240/480.
What is the freon R-134a capacity for a 96 Lumina AC 3.1 motor?
ive got the 97 3.1 and its rouhgly 30oz.
When was the first maglev train invented?
Electromagnetism was discovered in 1911 and it led to the mag-lev trains. These trains made rail travel much faster and used less energy.
How do you hook up a 3 phase water heater to a 3 wires 1 white 1 black 1 bare copper ground?
In order to answer your question, firstly, we have to accurately establish your supply.
Is it 2 phase or 2 wire?
2 phase is two active conductors, i.e. 2 live wires with reference to neutral or ground
2 wire is single phase, an active and a neutral conductor.
2 phase supply is uncommon.
Single phase (2 wire) is the more common supply and for installations with large loads three phase, or, more appropriately 3 phase and neutral (4 wire) is used.
Please confirm your supply so that a detailed answer can be provided.
Can you replace 1.7 microFarad capacitor with 2 microFarad capacitor of capacitor start motor?
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
It can't, unless there's some other coil, such as a bunch of wire between the two, or you're measurement equipment is off. Two inductors in series will have the same inductance as the two summed together.
What are the uses of power system stabilizer?
PSS is a part of AVR in the form of an algorithm which detects and helps in damping of power system oscillations.
Why is sma welding current referred to as constant current?
because the current is regulated rather than the voltage
all the motions are controlled by movement that has been programmed.
you cant see whats going on with the arc so to make adjustments you have to reprogram the motion after you stop and see what happened.
perhaps you can set it for constant voltage and get better results.
perhaps constant voltage is better for different materials.
most smaller wire feeds are constant voltage which tends to keep the arc length constant.
the operator can watch what he doing if he can see the arc and can make all manner of small adjustments. without reprogramming the controls.
stick welding is possible because you can watch what you are doing to keep arc length constant the machines are almost always constant current
Why is your consort ev265 power supply reading low current and power?
A Consort EV265 power supply will begin reading low current and power during component failure like capacitors and resistors. When the appropriate amount of power is not flowing, readings and power output will fluctuate.
Why bounce proof contacts are used in relays?
Simply because - relays are designed to be single-use switches. If they were able to 'bounce' they could re-establish a connection, which might cause the circuit to fail.
How electrical devices in homes give off small amount of heat true or false?
True that electrical devices generate some amount of heat.
