1. What is Rectification?
Rectification is the process of converting alternating current (AC) into direct current (DC). It is done using rectifier circuits that allow current to flow in only one direction.
2. What is Half Wave Rectification?
Half wave rectification converts only one half of the AC cycle (positive or negative) into DC. It uses a single diode and is less efficient than full wave rectification.
3. What is Full Wave Rectification?
Full wave rectification converts both halves of the AC cycle into DC using two or more diodes. It provides higher efficiency and a smoother output than half wave rectification.
4. What is Crystal Diode?
A crystal diode is a PN junction semiconductor device that allows current to flow in one direction. It is commonly used in rectification due to its small size and reliability.
5. What is Forward Resistance in Diode?
Forward resistance is the resistance offered by a diode when it is forward biased. It is usually very low, allowing significant current to pass through with a small voltage drop.
6. What is Reverse Resistance in Diode?
Reverse resistance is the resistance offered by a diode when it is reverse biased. It is very high, allowing only a small leakage current to pass through the diode.
7. What is Forward Current?
Forward current is the current that flows through a diode when it is forward biased. It increases rapidly once the applied voltage exceeds the diode’s knee or threshold voltage.
8. What is Peak Inverse Voltage?
Peak inverse voltage (PIV) is the maximum voltage a diode can handle in the reverse-biased condition without breaking down. Exceeding this limit may permanently damage the diode.
9. What is Leakage Current or Reverse Current?
Leakage current, also known as reverse current, is the small current that flows through a diode in reverse bias. It is usually very low unless breakdown occurs.
10. What is Rectifier Efficiency?
Rectifier efficiency is the ratio of DC power output to AC power input. It shows how effectively a rectifier converts AC to DC and is usually expressed as a percentage.
