How power is flowing when voltage and phase angle is maintained same?
Assume you are saying that the current and voltage are in phase and you want to know how power is affected. When Voltage and Current are in phase the Power Factor is 1 and you have maximum power being applied. When Voltage and Current are not in phase, Power Factor decreases from 1 toward zero.
Why the current is low when the voltage is high?
In principle it is possible to have any combination of voltage and current that you want, provided that you have the generating capacity to create it, however, it is also true that in some circumstances you get lower current with higher voltage, because you started with a moderate current at moderate voltage and put it through a step-up transformer to increase the voltage, which it does at the expense of the current.Additional CommentsIt's important to realise that the current supplied by a generator is determined by the load. The generator does not 'push out' current -the current is 'pulled out' by the load. With no load, the generator will supply voltage but there will be no current.A transformer is used to step up, or to step down voltage. Because the output (secondary) power is practically (but not quite) equal to the input (primary) power, one side of the transformer has a high voltage and a low current, while the other side has a low voltage with a high current -but, in both cases, the current is determined by the load, not the generator, nor the transformer.
How can instantaneous current values be determined?
Voltage divided by the resistance of what ever you want to measure the current in.
How current increases when the load increases in a generator?
Power is voltage times current. If you want to maintain constant voltage and yet increase power, then current must increase. Its simple math.
How do you convert low voltage into high voltage without using transformer?
Low voltage can be turned in high voltage by using so called transformers,wich are made by coils and iron.When a voltage passes it it will get a high voltage out of it.Exaple a 6v can be turned into 300v and using this idea,cameras wok with the same prinicple.By using two transformers they converst 6v to 300v than to 5000v,incredible,isnt it.
What kind of math do you need to be an electrician?
Arithmetic and basis algebra are good skills to have. For example, Ohm's Law says Voltage = Current x Resistance. If you know Resistance and Voltage and want to solve for current you need to know that Current = Voltage / Resistance.
Can you use a high voltage capacitor on a low voltage battery?
Yes. You just don't want to exceed the voltage rating of the capacitor.
What is the science behind the alternating current?
When a sinusoidal alternating voltage is applied in a circuit, the resulting alternating current is also sinusoidal and has the same frequency as that of applied voltage .However, there is generally a phase difference between the applied voltage and the resulting current.This is how alternating-current circuit works.

How many things are needed to create a current?
A difference of potential (voltage) and a conductor connected to the voltage source will cause current flow. Not that you'd want to "short out" a voltage source with a piece of wire, but just the source of voltage and the conductor would permit current to flow. If you took a piece of wire and touched it to the terminals of a good battery, current would flow. It takes just those two things to create a current.
How do you calculate current in a series circuit?
voltage over resistance/impredance. V / I * R V= Voltage I= Current R= Resistance or Impedance Cover what you want to know and the way the other two are laid out gives you your equation.
How many DC volts of solar power would it take to suppy a home 3500kWh?
Power = voltage * current. Without current, relating voltage to power is meaningless. One thing I can say is the voltage should be dictated by the amount of losses that is acceptable - the cabling you use to transfer the power to your home will have a specific resistance per unit length, which is unchanging. If you choose to use a low voltage, you will in turn use a fairly high current to transfer the energy you want. The power lost in the cable will be P = R * I^2. This loss can become significant, dictating a higher voltage.
What is the use of universal high resistance voltmeter?
A voltmeter must have a very high resistance to measure voltage. A voltmeter is placed in parallel with the element that you are measuring. If the voltmeter has a low internal resistance, then all of the current will flow through the voltmeter instead of the element. You want all of the current to flow through the element, to get an accurate reading of the voltage. Conversely, an ampmeter must have zero resistance, because it is placed in series with the element.
