What else can I help you with?
The highest value reached by an alternating voltage in a half cycle is called?
maximum or peak value
What is transient voltage?
A transient voltage is a time varying voltage value. Transient says that the voltage value changes, especially from a steady state, to a new value, then back again.
How does the peak value of an alternating voltage compare to its quoted value?
The quoted value is usually RMS value, i.e it is lesser than the peak value of the voltage, therefore the peak value is sqrt(2) times the quoted value. (it is a sine wave)
What is average value in alternate voltage?
The term is 'alternating voltage', not 'alternate voltage'. For an a.c. voltage or current, the average value is taken over half its wavelength because, over a complete wavelength it is, of course, zero. For a sine wave, the average value (over half a wavelength) is 0.637 Vmax or 0.637 Imax.
What is it mean to say that an alternating current leads or lags an alternating emf?
It is another way of saying that the circuit is capacitive reactive circuit. Look up the mnemonic ELI the ICE man. ELI, voltage leads the current in an inductive circuit. ICE, current leads the voltage in a capacitive circuit.
What is alternative voltage?
Alternating voltage is the E.M.F. and is one whose magnitude whose magnitude changes with time and direction reverses periodically. The instantaneous value is given by E=Eo sin w t, where,E=value of alternating voltage at time t Eo = maximum value of alternating voltage(amplitude) w=angular frequency of supply.
What is the difference between a transformer and a rectifer?
A transformer is used to change the value of a voltage applied to the transformer's primary winding to a different voltage value taken from the transformers secondary winding. A rectifier is used to change an alternating current value to a direct current value.
What is rms value in ac system?
The r.m.s. value of an alternating current or voltage is the value of direct current or voltage which produces the same heating effect.
The highest value reached by an alternating voltage in a half cycle is called?
maximum or peak value
What is diffence between ac volt?
AC is short for alternating current and DC is short for direct current. In the case of an AC signal the current is going backward and forwards at the rated frequency of the signal (so 240V at 50Hz would mean the terminals vary between 240V and -240V and back again 50 times a second). If you were electrocuted by AC you would be repelled away from it. In the case of a DC signal the current is in one direction and the voltage will remain either positive or negative (so a 240V signal would stay at 240V and the current would flow positive to negative - conventional current). If you were electrocuted by DC you would stick to it and probably suffer some serious burns, which is one reason for high voltage electrical supplys being AC. I hope that answers your question!
How does the voltage across a load is measured in a circuit with alternating current?
The voltage across a load in a circuit with alternating current is typically measured using a voltmeter. The voltmeter is connected in parallel to the load, allowing it to measure the effective voltage or RMS voltage across the load. This value represents the average voltage of the alternating current waveform.
What is transient voltage?
A transient voltage is a time varying voltage value. Transient says that the voltage value changes, especially from a steady state, to a new value, then back again.
How does the peak value of an alternating voltage compare to its quoted value?
The quoted value is usually RMS value, i.e it is lesser than the peak value of the voltage, therefore the peak value is sqrt(2) times the quoted value. (it is a sine wave)
What is the instantaneous value of AC?
The instantaneous value of an alternating current (AC) is the value of the current at a specific moment in time. It is constantly changing direction and magnitude due to its alternating nature, so the instantaneous value represents its value at that precise instant.
What is RMS Peak value and average value?
RMS is used to determine the average power in an alternating current. Since the voltage in an A/C system oscillates between + and -, the actual average is zero. The RMS or "nominal" voltage is defined as the square root of the average value of the square of the current, and is about 70.7% of the peak value.************************************************************The r.m.s. value of an alternating current or voltage is the value of direct current or voltage which produces the same heating effect.Fo a sine wave, the r.m.s. value is 0.707 x the peak value.The average value is different; for a sine wave it is 0.636 x the peak value.
What is average value in alternate voltage?
The term is 'alternating voltage', not 'alternate voltage'. For an a.c. voltage or current, the average value is taken over half its wavelength because, over a complete wavelength it is, of course, zero. For a sine wave, the average value (over half a wavelength) is 0.637 Vmax or 0.637 Imax.
How does ac current differ from DC?
AC current fluxuates that is why it is called alternating current. DC does not fluxuate that is why it is called direct current.Better answer"DC does not fluxuate that is why it is called direct current."If I waggle the voltage control up and down on a d.c. power supply to which a resistor is connected, the current willfluxuate. (Quite poetic, but I prefer to say fluctuate.)An a.c. changes direction rapidly and continuously, i.e. its direction alternates.That's why it is called alternating current.AC current Or alternating current is constantly switching from plus to minus While DC current or direct current moves from minus to plus.AC and DC refer to Alternating Current and Direct Current respectively. AC is the movement of electrons through a conductor while switching directions, while DC involves electrons moving steadily in a particular direction.
