Most computer power supplies contain both. The Transformers are usually toroidal transformers for high efficiency and compactness.
What else can I help you with?
Which is found in a PC power supply Transformer or rectifier?
A rectifier is a device that converts AC to DC.A transformer is a device that changes the ratio of current to voltage.A computer power supply functions as both.Answer found in CompTIA A+ Guide to Managing and maintaining Your PC 6th edition on page 154.
What is the difference between a transformer and a rectifierwhich are found in a PC power supply?
The rectifier is what changes your AC into DC that the computer can use. Transformer raises or lowers the voltage. So you have 110 volts AC coming into your computers power supply. The Rectifier circuit in there changes the AC voltage to DC voltage but it is still to high for the computer use. The transformer lowers that voltage down to the various voltages that your computer needs
4 What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A rectifier is a device that converts alternating current to direct current. A transformer is a device that changes the ratio fo current to voltage. A rectifier is found in a PC power supply.
What is the difference between a transformer and a rectifier Which are found in a PC power supply?
A transformer is a device that changes the level of an a.c. voltage, while a rectifier is a device that converts alternating current to direct current.
What is the purpose of the transformer in the half-wave rectifier circuit?
what is the function of transformer in the half wave rectifier circuit
How are is a transformer and a rectifier different?
A transformer changes the VOLTAGE of AC current (AC to AC). A rectifier changes AC to DC.
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
Can the two end of a center tap transformer be use with out a rectifier?
The twoends of a center tap transformer cannot be used without a rectifier.
Is a transformer used in full wave rectifier?
A full wave rectifier is a component or set of components that change AC waveforms into DC. It is frequently used as part of a power supply circuit and therefore it is often directly adjacent to a transformer. However, a transformer is used to provide a suitable AC voltage and is not part of the rectifier.
Is there any application where center tap rectifier is preferred over bridge rectifier?
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
Why transformer use in mid point cycloconverter?
For decrease the rectifier number
Does a transformer rectify the alternating current?
No, a transformer changes the ac to a voltage that the user requires. After that a rectifier can be connected to it to provide dc.
