What is the voltage that comes out of power stations?
Let's look at this from a from a simplistic point of view. When working with electricity, power is a combination of amperage, and voltage. Amperage drops significantly with distance, voltage does not. Because of this, a power plant generates its power as a combination of a huge voltage with very little amperage. Therefore, the power loss over long distances is minimized. Power station voltages are in the hundreds of thousands of volts. However, these voltages are too dangerous for everyday use. Thus, they are transformed down to lower voltages such as 120 for household use, 480 for industrial, and other voltages. During power transformation, power is not lost. Thus, if you decrease the voltage, then your amperage goes up to provide the same power.
How can you view page by page output in c plus plus?
Pipe the output to the MORE command.
What output device allows you to view your work as you do it?
A monitor allows you to view your work as you do it.
Why is it necessary to use two channels on a oscilloscope to view the entire secondary voltage?
to maintain the same secondary voltage output from the transformer the primary transformer is wound for operation but it is split exactly in the centre.when used as an ac the two half of the primary are connected in series producing the designed output from the secondary.example if used on a 120v line the 2 halves of primary are connected in parallel producing 25v from the secondary and paver(vA) at of the transformer is the same

Where a page output is wider than it is tall?
That is call the Landscape view.
What is the output of the man command in Linux?
man has no output of its own. You must specify the name of the manual page you wish to view. For instance, to view the manual for bash, you would use the command man bash.
Meaning and examples of output device?
An output device is a device which is used to view data given out by a computer, be it a printer, monitor or speaker.
Is the heat loss and current of a resistor affected by being in a parallel circuit or can you just calculate it the same as in series?
The heat generated by any particular resistor depends (at least electrically) solely on the power it dissipates. Power dissipation in a resistor is equal to current squared times resistance, and the current through the resistor is equal to the voltage across it divided by the resistance. If we take a 10 ohm resistor ('your resistor') and put it in a series circuit such that there is 10 volts across your resistor, the current through it will be 1 ampere (10/10=1). the power dissipated will be 10 watts (1^2 * 10=10). If we put your resistor in a parallel circuit that also puts 10 volts across it, then the current and power will be the same. Your resistor does not know or care where the voltage came from. From this point of view, once you get down to the voltage across the resistor, it does not matter what type of circuit it is in. On the other hand, for any given power supply voltage, then the type of circuit and the value of external components certainly does affect the terminal voltage and thus the current through as well as the power dissipated by the resistor. In a parallel circuit, the voltage across your resistor remains basically the same no matter what resistance you put in parallel with it (unless you overload the power supply or the power supply has high internal resistance). In this case, the voltage across the resistor is the same as the power supply, current is I=E/R, R being that resistor only, and power is P=I^2 * R. In a series circuit the current through the resistors is I=E/R, R being the total resistance (including the other resistor(s)). The power dissipation in your resistor will then be P=I^2 * R, I being the series current we just calculated, and R being your resistor only. Since the other resistors affect the current, and since the current is the same no matter where you measure in a series circuit, then the voltage across your resistor and thus the power dissipation will be affected. The voltage across your resistor will be E=I*R, I being the series current we just calculated, and R being your resistor only. So, while the calculation for power dissipated in a particular resistor does not change relative to what type of circuit it is in, the calculation to arrive at the voltage across the resistor and/or the current through it (which you will then need to calculate power) does. Keep in mind there are other mechanical parameters that influence the actual case temperature of the resistor. Physical size of the case, composition, and airflow velocity, if any, will alter the case-to-ambient thermal conductivity. Ambient temperature will also be a factor in the final temperature.
Why is it more difficult to to measure the high power field of view than the low power field of view?
The High powered field of view is harder to measure.
Is the field of view brigther under low power or high power?
the view will be brighter under low power magnification...
What is voltage regulation?
Voltage regulation:(from point of view of electrical machines or generator): It is the change in voltage in between the full loaded and no loaded condition. When there are no loads connected the terminal voltage is equal to the generated voltage in the generator. But when load is connected the terminal voltage is found to be lass than the no loaded condition, due to armature resistance leakage reactance.This phenomena is expressed as, % reg=(Vnl-Vfl)/Vfl * 100%.Which is Voltage regulation. ************************************************************ An ideal voltage source has zero internal impedance. A practical one, even a good one, has internal impedance. With no load on the source, the terminal voltage will have a given value. Once a load current is drawn there will be a voltage drop across the source's internal impedance, and the terminal voltage will therefore drop. The higher the load current, the higher the voltage drop. A regulator circuit, added after the source, can counter the effect of the source's impedance and maintain an output voltage which is more constant than the source itself can achieve.
