You can make it so it does either increase or decrease. The limiting factor is that power out cannot exceed power in. So going to a higher voltage will limit current and going to a lower voltage will increase current available.

Because AC is continuously changing in a sinusoidal waveform, it is hard to determine the exact voltage. It is usually called by it's RMS value (Root Mean Squared).
The result is that when you fully rectify an AC voltage, the DC voltage is actually HIGHER than the RMS AC voltage.

Who to increase torque of ac motors?
ac voltage
What component of a welding machine changes AC current to DC current?
Yes, it is normal for a welding machine to convert AC voltage to a DC voltage.
What device is used to increase or decrease the voltage of an alternating current?
A transformer is the device used to increase or decrease the voltage of alternating current (AC) This is done through a process referred to as inducing.It's operation is based on the fact that electricity produces a magnetic field around itself. By placing 2 coils of cable beside each other, the magnetic field of one coil will induce a voltage in the other coil.
What is the difference between a voltage converter and a voltage inverter?
Converter is AC to DC. Inverter is DC to AC
What is the effect in output for changing input frequency in halfwave rectifier?
if filtered and loaded the average DC voltage will increase and the ripple AC voltage will decrease, but the peak voltage is unchanged. this is because the filter capacitor has less time to discharge into the load.if unfiltered or unloaded the voltage cannot change. unfiltered the waveform just follows the half cycle of the input. if filtered but unloaded the output is DC at the peak voltage of the input AC.
Can you increase or decrease an ac voltage?
yes, by stepping it up or down with a transformer.
How do you convert 23 voltage DC to 230 Voltage AC?
How do you convert 23 voltage DC to 230 Voltage AC?
Why doesn't a transformer convert AC into DC?
transformers increase or decrease voltage. converters have rectifiers inside, which change ac to dc Transformers are devices that operate on the change in magnetic field, That change in magnetic field only induces an AC voltage/current into the secondary winding. From there it must be rectified to obtain DC, and is very often filtered to make it usable.
Why is rectification needed?
To convert AC voltage to DC voltage.
Who to increase torque of ac motors?
ac voltage
Is tranformer used to increase or decrease AC voltage?
The function of any transformer is to change one AC voltage value to another AC voltage value. A step down transformer will transform a higher AC voltage to a lower AC voltage. A step up transformer will transform a lower AC voltage to a higher AC voltage. The transmission of electrical power uses both of these types of transformers. From the generation station the voltage is stepped up to a very high transmission voltage and at the end of the transmission line it is stepped down to a voltage that consumers can utilize.
Is the capacitor used in the ac system to reduce line voltage?
Usually capacitors in an AC system are there to improve the power factor. Transformers are used to increase or decrease line voltages.
Does centre tap transformer convert ac voltage to ac voltage?
Yes. Transformers convert power by stepping up or down voltage. It doesn't matter what tap configuration they have.
How do you increase or decrease voltage?
This question makes no sense as written. However, maybe it will help to know that for a given load if you increase voltage the current increases proportionally and if you decrease the voltage the current decreases proportionally. Ohm's Law says Voltage = Current x Resistance.
Why ac drive convert ac voltage in dc?
It is done to control the speed of the motor.
Which component slow down the current in circuit?
An inductive load can cause current to lag voltage in an AC circuit. An increase in resistance will decrease amount of current flow.
How do you conyert AC to DC?
You rectify AC voltage through a diode bridge to convert it to DC.
