FAQ

Those interested in the Ac vs dc sine wave category often ask the following questions:

☑️ Is a sine wave ac or dc?

An AC supply is suitable for powering some devices such as lamps and heaters but almost all electronic circuits require a steady DC supply (see below). This shape is called a sine wave. This triangular signal is AC because it changes between positive (+) and negative (-).

☑️ Can dc be a sine wave?

DC circuits have a unidirectional flow of current and like AC it is not changing the direction periodically. Waveform of DC is a pure sine wave. As you can see, the voltage is constant with respect to time.

☑️ Is triangular wave ac or dc?

The wave form produced by an AC circuit can be : Square wave ,Triangle wave or Sawtooth wave .

☑️ Why is ac a sine wave?

But in basic circuit analysis and AC signal analysis, we tend to use sine waves because they are the easiest to generate (as compared to square/ramp signals) as well as the easiest to analyze mathematically (all our calculus tools work wonderfully for curves like the sine, but tend to be more inconvenient around things ...

☑️ Is a square wave ac or dc?

The 240 volt mains power supplied by the electricity grid is AC (Alternating Current)… "Square wave" is the term used when the electricity has a constant force, such as it has with DC but switches direction more or less instantly at the same kind of frequency as the normal grid supply (at 50 times per second).

How to convert ac to dc using half wave rectifier?

Why is an ac always positive and negative sine wave?

It is because, sine wave can be easily produced mechanically (at power stations) compared to other forms of waves. +++ Further, alternating voltage is readily stepped up or down by transformers, something you cannot do with DC, but a very important practical property of AC electricity.

Can a ac motor run on a modified sine wave?

  • Some AC motors will run on modified sine, but there is a risk of heat buildup that could damage the inverter, appliance or both. This may or may not happen, so check the appliance owner’s manual for what inverter it works with. Medical equipment like CPAP and oxygen concentrators work best with pure sine wave.

Why is the average voltage of an ac sine wave zero?

  • Keep in mind that the average voltage value of full AC sine wave is zero because the area covered by poitive half cycles is equal to the area covered by the negative half cycle which cancel each other. That’s why we can’t use AC to store in batteries.

Why you use sine wave for ac power supply why not triangle wave or square wave?

AC power comes from an electrical generator, which is a set of stationary coils (the stator) around a rotating magnetic field (the rotor). This configuration produces a sinewave output. We use a sine wave on the power grid because that's the way the electricity is generated, and it is a "natural" thing to do. It's a "pain" to have to convert it to another waveshape. There is also the fact that some nasty harmonics will appear on the power grid if we try to use triangular or square waves. Particularly with a square wave. The electrical loss will be higher, too. See the generator link below. Additionally, the sine wave is the the 'purest' waveform, being the root of all other period waveforms. See Fourier series link below.
