ples answer
The mean load voltage, in other words the average voltage, is zero in an ac system.
the answer is Rectifier. it converts ac voltage into dc which can apply to the dc device
Kirchoff's Voltage and Current Laws apply to all AC circuits as well as DC circuits. Other laws, such as Ohm's law and Norton and Thevanin equivalents apply equally as well. The complicating factor is that, at AC, current and voltage are not usually in phase with each other, unless it is a simple resistive circuit. That makes the math harder, but it does not make it invalid or impossible.
we can apply 230v ac to kbpc2510 maximum peak voltage is 325v (for 230v) and its blocking capacity is about 1000v so we can use it (I used for the same application)
How to test a diode bridge ? Diode bridge is a device is used to convert an AC signals (say AC voltage) to DC output (say DC voltage). So, to test it, you can apply a AC voltage v = Vm Sin (wt) at its 2 inputs and measure DC output voltage Vdc.
the work is done in the power supply box (the metal box part in the computer, the one you plug the power cord into). It converts AC to DC via transformers, rectifiers, and voltage regulators and has extra circuitry in there to make sure that the voltage doesn't ripple (with the changes in the AC voltage) or spike (e.g., when you first turn it on)
A coil has both resistance and inductance. When you apply a d.c. voltage, the opposition to current is the resistance of the coil. When you apply an a.c. voltage, the opposition to current is impedance -the vector-sum of the coil's resistance and its inductive reactance. Inductive reactance is proportional to the inductance of the coil and the frequency of the supply.

How do you convert 23 voltage DC to 230 Voltage AC?
rms voltage will give the ability to predict how much work will be done by an ac voltage. the rms value of a pure sine wave is 0.707 times it's maximum amplitude.
Voltage AC was created on 2004-12-14.
AC voltage is varying because it is sinusoidal in nature
