Is 30 volts of AC voltage the same as 30 volts of DC voltage?
30VAC is not equal and will never be equal to 30VDC. If you rectify 30v ac to DC you will get a voltage lower than 30v because there would be a voltage drop across the rectifier=diode,capacitor,resistor and transistors or thyristor, depending on the make of the rectifier.AnswerAs the questioner makes no mention using a rectifier, yes, 30 V a.c. is exactly equivalent to 30 V d.c. This is because a.c. voltages are root-mean-square values (unless otherwise stated) which, by definition, correspond to d.c. voltages.
How can you 120 volts AC to 5 volts DC?
By a DC power supply that runs at 230 volts AC. Basically, you need a full wave rectifier (4 diodes) to convert AC into all positive voltage. Then you need capacitors to smooth out the ripple and then various resistors to reduce the voltage.
Why freqvency in AC and Why not in DC Voltage?
In AC voltage, frequency refers to the number of complete cycles per second that the voltage alternates direction. This is because in AC voltage, the direction of current flow continuously changes over time. In DC voltage, there is no alternation of direction, so frequency is not applicable.
What is the household ac electrical power mains voltage in Italy?
The voltage is 230volts and this is the norm in Europe.
What is my 240 v supply at home ac or dc?
The household supply in the UK is 240 V and is AC (alternate current).
Why is voltage regulation of dc line is better than ac line?
in dc circiuts only resistors are responsible for voltage drop. where as in ac circuits inductances and capacitances are also responsible for voltage drop in addition to that of ressistors
What are the differences in voltage drop between AC and DC systems?
In AC systems, voltage drop is affected by factors like resistance and reactance, leading to a more complex calculation. In DC systems, voltage drop is mainly influenced by resistance, resulting in a more straightforward calculation.
How do you test a diode bridge?
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.
When doing an insulation resistance test on an electrical circuit do you test at 500v dc or 500v ac?
dc insulation test = 2 * operating voltage +1000V ac insulation test = 2* operating voltage impedance of long wires or cables make ac testing sort of impractical dc test will never be lower than 1000V
How do you connect and test exciter voltage?
To start the ac motor at starting by exciter.
What value of resistor would take you from 18v ac to 3.3v ac?
sorry - no can do. The value of a resistor is dependent upon the amount of current flowing through it. To drop the a.c. voltage as you have stated would require a drop-down transformer.
ABS sensor produce AC voltage or DC voltage?
AC !
How does a voltage regulator regulate the voltage output of an ac generator?
Generator output is controlled by voltage feedback to the voltage regulator which senses voltage drop or rise and regulates the current being sent to the armature. This rise and fall of the armature current governs the generators output voltage.
Why do my lights flicker when my AC turns on?
When your AC turns on, it draws a lot of power, causing a temporary drop in voltage. This drop can make your lights flicker because they are momentarily receiving less electricity than they need to stay fully lit.
How does the variation of excitation of an alternator correct power factor?
The rotor of an alternator need a DC voltage applied to it to generate a magnetic field, this magnetic field will generate the AC power in the AC windings.The AVR(Automatic Voltage Regulator) is regulating this DC voltage so that the magnetic field is strong enough to maintain the output AC voltage. As soon as more current is drawn from the output, this output voltage will drop and a stronger magnetic field is needed to sustain the output voltage, so the AVR step up the exiting voltage to get a stronger magnetic field to compensate for the voltage loss in the AC windings.
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
What is the effect of long armoured cable used for star delta starter for 3 phase ac motor?
voltage drop is be a problem.
