While there are no true voltage sources, some reasonable approximations of them exist:
- DC, any type of battery
- DC, voltage regulated power supply
- AC, wall outlet
- AC, true sine-wave UPS
- AC, variable frequency sine-wave signal generator
- etc.

What happened to DC voltage source which is in series with AC voltage source?
The two sources add together, imposing a DC bias to the AC source.
How do you find effective value of a current?
The effective value of an AC = AC/√2. Example: the effective value of 8.5 V AC is 6.01 V, because 8.5/√2=6.01 Hope that helped :)
Why synchronous motor called double excited motor?
AC and DC supply sources we are given to motor so we are called double excited motor
How can you differentiate DC and ac?
DC is direct current. It is characterized as a voltage or current that is constant or, more precisely, always in one direction. A battery is an example of a DC source. AC is alternating current. It is characterized as a voltage or current that is alternating, i.e. changing direction at some frequency such as 50Hz or 60Hz. The power supplied to your home from the public power utility is an example of an AC source. ac is attractive in nature while dc is repulsive .
Rms value defination?
Because alternating current (AC) voltage varies over time, to the positive and negative, an actual AC voltage measurement will not be the same as a DC voltage measurement. For example: 5 volts DC is 5 volts constantly, viewed over time. The average voltage is 5 volts. 5 volts AC (from zero to peak) is not actually 5 volts constantly, but varies between 5 volts and 0 volts over time. The average voltage will not be 5 volts. Using RMS AC values is designed to make AC and DC measurements equivalent, for example 5 volts DC and 5 volts RMS AC are almost identical.
How does an ac power source differ from a dc power source?
AC power sources are the adapter power sources. DC power sources are the direct power sources. DC stands for direct current, meaning it is a direct source of energy., and AC stands for alternating current, which means it is a secondary source of power.
What is the energy source for an AC current?
The energy can come from many different sources.
What are example of sources?
lasers
What happened to DC voltage source which is in series with AC voltage source?
The two sources add together, imposing a DC bias to the AC source.
Where do chloroflourocarbons come from?
They come from various sources. AC's, deodorants etc are some examples.
Does combining ac power sources double the voltage?
This is not a Yes/No answer, as the answer depends on the AC power sources used. There are two factors: - Frequency: e.g. in the USA the powergrid its AC frequency is 60Hz - Phase: an AC power source its voltage rises up and down with a certain frequency. When you take 2 AC sources, Phase is the shift between those two (this is often expressed in an angle). If the AC power sources have the same frequency and there is no phase shift, then the AC Voltage will double when you serialize the two. However, If the two sources are 180 degrees (or PI radians) out of phase, then they will cancel each-other out. Imagine AC current like the ripples in a pond when you throw 2 stones in the water 2 feet apart: The ripples flow out in a circular pattern from the center of the spot where a stone hit the water. Where the 2 circles meet, you'll notice that a some spots there is no activity (the ripples cancel each other out) and at other spots the ripples are higher.
Which sources produce alternating current?
AC generators, powerplants etc produce alternating currents.
What are the two power sources that power a laptop?
* Electric Power * battery
What is the difference between general reference sources and special reference sources?
differentiate general reference sources and special reference sources with example
Why do you study dc analysis first before ac analysis?
We do study DC Analysis first before AC Analysis for the sake of simplicity, for pedagogic reasons, and also for historic reasons. As useful and as easy to understand as DC is, it serves as a preparatory ladder in studying the more complex behavior of AC. In addition, it is to respect the historical sequence of events since DC sources were first discovered before the AC sources.
Can you give an example of sources of electricity?
battery
Can you give a catchy slogan on conventional and non conventional sources?
"In Good Hands" is an example of a catchy slogan on conventional sources. "American By Birth Rebel By Choice" is an example of the non-convectional sources slogan.
