What is alternating current produced by?
Alternating current is produced by generators or power plants that use magnetic fields to induce voltage and generate electricity. This type of current changes direction periodically, typically in a sinusoidal waveform.
What are the phasor diagrams and sinusoidal expressions of the three voltages?
Phasor diagrams represent the amplitude and phase relationship of the voltages in a three-phase system. The sinusoidal expressions for the three voltages can be represented as: V1 = Vmsin(ωt), V2 = Vmsin(ωt - 120°), V3 = Vm*sin(ωt + 120°), where Vm is the maximum voltage and ωt represents the angular frequency of the voltages.
How can a pendulum be used so as to trace out a sinusoidal curve?
A pendulum can trace out a sinusoidal curve by swinging back and forth under the influence of gravity. As the pendulum swings, it undergoes simple harmonic motion with a sinusoidal pattern, where the displacement of the pendulum from its resting position follows a sine wave. By recording the position of the pendulum at different points in time, you can create a graph that shows a sinusoidal curve.
True or false Moving current has electrical energy?
It is true that moving current has electrical energy.
A current that moves back and forth is?
An alternating current (AC) is a type of electric current that changes direction periodically. It moves back and forth in a cyclic manner, typically in a sinusoidal waveform. AC is commonly used in household power supply systems and many electronic devices.
Why The Excitation current is non-sinusoidal when applied voltage is sinusoidal?
excitation voltage is sinusoidal because it is taken from the terminal of alternator but excitation current is non-sinusoidal because it always dc.
What is nonsinusoidal currents?
"nonsinusoidal current" is any current that is not sinusoidal - it could be a wave such as a square wave, triangle wave, etc. DC (direct current) is non sinusoidal. This term is often used in reference to currents that you "would expect" to be sinusoidal (such as the current to your house is sinusoidal at 50 or 60 hz) but aren't - such as transformer inrush current, magnetizing currents,...any current with large amounts of harmonics. AC current is also (generally) not sinusoidal due to the way power supplies only conduct from the input when the rectifier filter capacitor needs to be recharged during each line cycle. That results in a pulsing current, even though the voltage is mostly sinusoidal.
Why alternate current is taken as sinusoidal wave why not ramp or step wave?
sinusoidal Wave is the description of the shape that is seen on a oscilloscope display of, for example, true "House Current" The ramp wave form and step wave form are sharply different in shape and can cause problems with some electrical devices
No load current of transformer is non sinusoidal even though sinusoidal voltage is provided in oc sc test?
eddy current loss in the transformer core is reduced by
Why the waveform of no load current is not sinusoidal?
No load current is mostly inductive, hence the load current may not be a sine wave
What are the differences between sinusoidal oscillators and non sinusoidal oscillators?
sinusoidal vs non sinusoidal
What is sinusoid?
What is a sinusoidal wave? This is a wave that appears to have curves. AC current/voltage. If you see a wave on a ossiloscope of what our AC (Alternating current) mains voltage that will be the answer to the question. DC (direct current) does not appear to have the same qualitys
Explain the power supply circuit for conductivity electrode?
You have to excite it with a sinusoidal signal then measure the current or voltage
Why ac current is sinusoidal or is in a wave form?
I m confuse in ques. Plz chng thd ques.
Find the effective values sinusoidal waveforms?
effective values = Vm/SQR(2) max voltage / the square root of (2) same for current This doesn't apply for all periodic functions, only sinusoidal.
Why the transformers input current is non sinusoidal?
The input current of a transformer is non-sinusoidal primarily due to the presence of non-linear loads connected to the transformer, which introduce harmonics into the system. Additionally, the transformer itself can exhibit non-linear characteristics, especially when operating near saturation or under varying loads. These factors result in a distorted current waveform that deviates from a pure sinusoidal shape, leading to increased losses and potential overheating in the transformer and connected equipment.
Why must you use ac current for transformer?
Transformer is based on the principal of mutual inductance.Induction is produced due to sinusoidal wave form thats why we use Alternating current inspite of Direct current.
