Frequent question: Which one can be used as a rectifier Mcq?

What is a rectifier used for MCQ?

Rectifiers – Electronic Devices and Circuits MCQs

Explanation: A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction.

Which device is used as a rectifier?

High-power rectifiers, such as those used in high-voltage direct current power transmission, employ silicon semiconductor devices of various types. These are thyristors or other controlled switching solid-state switches, which effectively function as diodes to pass current in only one direction.

Which circuit can be used as full-wave rectifier Mcq?

The bridge rectifier is a type of full-wave rectifier, which rectifies the complete waveform. It consists of three important components they are a transformer, four diodes, and load resistance. The diodes in the rectifier are connected in the form of a bridge and the main function of this is to convert AC to DC.

What is the most widely used rectifier?

A widely used rectifier is the three phase, 6 pulse, diode bridge rectifier. It’s main use is low voltage motor drive front end. The single phase uncontrolled full wave bridge rectifier circuit configuration (four diodes arranged in a bridge circuit) is the most widely used rectifier configuration today.

Which oscilloscope is used in a digital storage oscilloscope Mcq?

Which oscilloscope is used in a digital storage oscilloscope? Explanation: A digital storage oscilloscope makes use of a conventional cathode ray tube.

Why diodes are used as rectifier?

A rectifier is a device that converts an Alternating Current (AC) into a Direct Current (DC) by using one or more contact diodes. … Thus, the diode allows current in forwarding bias conditions and blocks current in reverse bias condition. In simple words, a diode allows current in just one direction.

What is rectifier Class 12?

Hint: A rectifier is a device or arrangement of electrical instruments which is used to convert AC (Alternating current) to DC (Direct current).

Is zener diode is used as?

A Zener diode is also known as a breakdown diode and it is mainly used as a voltage regulator. A Zener diode can be used as a voltage regulator or voltage stabilizer to provide a constant voltage from a source whose voltage may fluctuate over a wide range.

What is rectifier PDF?

• A rectifier is an electrical device that converts AC. supply into unidirectional DC supply. • This process of converting alternating current (AC) to. direct current (DC) is also called as rectification. • These bridge rectifiers are available in different.
