Why do we use diode?
The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking it in the opposite direction (the reverse direction).
Forms of rectifiers, diodes can be used for such tasks as extracting modulation from radio signals in radio receivers..
How does a diode convert AC to DC?
The diodes are connected to the two outer taps, and the center tap is used as a common ground for the rectified DC voltage. The full-wave rectifier converts both halves of the AC sine wave to positive-voltage direct current. The result is DC voltage that pulses at twice the frequency of the input AC voltage.
What is the current through the diode?
Current passing through a diode can only go in one direction, called the forward direction. Current trying to flow the reverse direction is blocked. They’re like the one-way valve of electronics. If the voltage across a diode is negative, no current can flow*, and the ideal diode looks like an open circuit.
How is a Zener diode used in a circuit?
Zener diodes are widely used as voltage references and as shunt regulators to regulate the voltage across small circuits. When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode’s reverse breakdown voltage.
What is the difference between a diode and a resistor?
A diode is a type of electrical device that allows the current to move through it in only one direction. … A resistor is an electric component that is used to provide resistance to current in the circuit. They are mostly used to produce heat or light. The two terminals of the diodes are known as anode and cathode.
What is the basic principle of Zener diode?
A Zener diode is a silicon semiconductor device that permits current to flow in either a forward or reverse direction. The diode consists of a special, heavily doped p-n junction, designed to conduct in the reverse direction when a certain specified voltage is reached.
What is a Zener diode typically used for?
Zener diodes are used for voltage regulation, as reference elements, surge suppressors, and in switching applications and clipper circuits. The load voltage equals breakdown voltage VZ of the diode.
What is the difference between a diode and a Zener diode?
Diodes are used to let electricity flow in a single direction through a circuit. Zener diodes differ from other types of diodes in that, when you connect them in the reverse direction in a circuit, such that current flows the other way across a diode, they let a small leakage current flow.
What is the current through the Zener diode with full load condition?
With no load connected to the circuit, the load current will be zero, ( IL = 0 ), and all the circuit current passes through the zener diode which in turn dissipates its maximum power.

What is the diode symbol?
Diode Symbol The symbol of a diode is shown below. The arrowhead points in the direction of conventional current flow in the forward biased condition. That means the anode is connected to the p side and the cathode is connected to the n side.
