Should 2 legs of 480 volt 3 phase each have 480 volts?
Across a 480 volt three phase system, 480 volts should appear across L1 and L2, L2 and L3 and L3 and L1.
How do you mesure leading and lagging factor?
Leading and lagging factors can be measured by comparing their impact on a specific outcome or goal over time. Leading factors are variables that change before the outcome, while lagging factors change after the outcome. By analyzing the correlation between these factors and the outcome, you can determine their level of influence and measure their effect on the desired outcome.
Frequncy is the speed of an electrical wave through a conducting material.for example a wave of frequency 50 Hz takes 20 milli seconds(1/50) to complete one cycle.
What are unbundled power rates?
Before, we did not know exactly how much goes to each particular service we are paying because our bill is bundled. For instance, since generation and transmission charges are not segregated, it is not clear to us how much goes to the cost of producing power and the cost transmitting this power to the distribution system.
With an unbundled bill, we will be able to see the cost for each service we are
paying. The unbundled electricity rate shows a longer list of items comprising
the cost electricity that we have to pay our electricity service provider.
It pays to know our unbundled bill. The more we know about the components
of our bill, the more we understand the rationale for unbundling electricity
rates mandated under the Electric Power Industry Reform Act (EPIRA)
of 2001.

the link in hvdc system is a conductor joining rectifier and inverter in series connection.
Answer'HVDC' stands for 'high-voltage, direct-current'. A HVDC link is widely-used for interconnecting independent high-voltage a.c. grid systems, such as UK/France. HVDC links eliminate synchronisation problems between the two a.c. grids.Electrical load forecasting. "A good electrical load forecast has a direct and significant impact on costly generating unit startups and shutdowns, energy purchases, managing system demand as well as scheduling system upgrades based on predicted load growth."
With a pure resistive load the Power Factor should be 1.
What does decrease after load mean?
Decreasing afterload refers to the reduction of the resistance that the heart must overcome to pump blood during systole. This can occur due to vasodilation or decreased vascular resistance, which makes it easier for the heart to eject blood. A lower afterload can improve cardiac output and reduce the workload on the heart, making it particularly beneficial in conditions like heart failure. This physiological change can enhance overall cardiovascular efficiency and support better perfusion of tissues.
Why the shape of the output characteristics curve for common emitter circuit are not equally spaced?
It is a non-linear device.
You have load 200Amp long 200meter how calculate voltage drop and what size cable can used?
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized

What is the purpose of the thrust wear down or low thrust oil pressure trip?
To prevent excessive axial movement of the rotor.
Why do you get a shock current when pushing a trolley?
There must have been a build up of static electricity, either in yourself or in the trolley. The shock is the spark as it makes its way to earth.
Without knowing the location of the capacitor in the amplifier (which you do not give) no specific answer can be given, only possibilities assuming various locations (e.g. input coupling, power bypass, bias networks, interstage coupling, virtual grounding of shields). Each will have one or more characteristic symptoms it could produce in the output.
How many resistors can be connected in series and parallel to get certain value of power?
As many as you need, and as many as space allows.
they are winding wound in such a way that they deliver three times the power
Definition of Quadrature axis?
Quadrature axis of a magnetomotive force is defined as that component of MMF that is directed along an axis in quadrature with the axis of the field poles. Quadrature axis of a magnetomotive force is defined as that component of MMF that is directed along an axis in quadrature with the axis of the field poles.
Why can you not calculate the total impedance of two impedance in series?
You can. Give an example, and someone here will help.
A backward induction is a process of reasoning backwards in time, from the end of a problem, in order to determine a sequence of actions to be taken.
