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 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 difference between amplitude and peak value?
It is the highest value of the amplitude, called the peak value. Scroll down to related links and look at "RMS voltage, peak voltage and peak-to-peak voltage". Look at the figure in the middle below the headline "RMS voltage, peak voltage and peak-to-peak voltage".
Does alternating voltage changes its value or direction?
AC voltage with no DC offset will change both it's voltage level (constant change, hence AC) and polarity (ie direction) every 1/2 cycle when it crosses zero.
What does the peak value of an alternating voltage compare to its quoted value?
Assuming "quoted value" to be RMS value, or average, [what you would see on a meter], the peak would be that value times 1.414. Going backward, peak times .707 is RMS.
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 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.

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 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 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 do you compare with a alternating current and a direct current?
The Alernating Current can be compared to a Direct Current using the AC's Root Mean Square value. That is about .707 times the Peak value, or the sin of 45 times the peak value or, 1 over the square root of two times the peak value. All three are the same essentially. This RMS value is like the average current or voltage that the load see's throughout one cycle.
