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 many kinds of voltage ssource?
There are primarily two types of voltage sources: DC (Direct Current) voltage sources and AC (Alternating Current) voltage sources. DC sources provide a constant voltage over time, commonly found in batteries and solar cells. AC sources, on the other hand, supply voltage that varies sinusoidally with time, typically seen in wall outlets and generators. Additionally, voltage sources can be classified as ideal or practical, with ideal sources having no internal resistance and practical sources having some resistance.
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 :)
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 .
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 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 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.
What are example of sources?
lasers
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.
What are coherent sources Give example.?
Coherent sources are sources of waves that have a constant phase difference between them. An example of coherent sources is two identical lasers emitting light waves with the same frequency and wavelength.
What are the two power sources that power a laptop?
* Electric Power * battery
Which sources produce alternating current?
AC generators, powerplants etc produce alternating currents.

An example of an AC source of power is?

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.
