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.
The difference between a transfer and a rectifier?
A transformer is basically used to step up or step down the main power supply. The rectifier is used to convert an alternating current (AC) or voltage to direct current (DC) or voltage.
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
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.
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.
Can you use transformer for DC supply?
No. Only Transformer could not be used for DC supply.If yoy need to have DC out put,then rectifier unit required .
What does filter do in a transformer?
A transformer does not use a filter. You may be asking about the use of a filter in a power supply. A power supply uses a filter to change pulsating DC from the rectifier into smooth DC for the circuits that the power supply powers.
What is the difference between control transformer and Potential transformer?
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
Does a transformer contains capacitor?
A transformer does not normally contain a capacitor. However, you might be thinking of a 'd.c. power supply', which consists of a transformer, rectifier, and smoothing circuits. The smoothing circuits will contain capacitors.
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
What type of transformer is used in rectifier circuit and why?
A step down transformer is used in rectifier circuits so as to bring the rectified voltage to within a reasonable value of the desired output voltage. It is a design decision, based on a compromise between various aspects of the filter and/or regulator that might follow the rectifier.
How does a rectifier transformer differ from a power transformer?
rectifier tr. is converting ac energy into dc energy. but power transformer converting step up or step down ac energy without changing frequency.AnswerA transformer and a rectifier are two completely-different devices. A transformer changes voltage levels, whereas a rectifier changes alternating current to direct current.There is no such thing as a 'rectifier transformer', although it is common for the output of a transformer to be rectified. Such combinations are widely-used in electronic components, where the mains supply must be changed to a low-voltage d.c. supply.The term, 'power transformer' is normally applied to step-up and step-down transformers used in the high-voltage electricity transmission system, as opposed to those used in the electricity distribution system, which are normally called 'distribution transformers'.
