Diodes & Rectification

The process of adding an impurity to an intrinsic semiconductor is called

• Doping

• Ionization

• Recombination

• Atomic modification

Doping of Semiconductors

• materials which can conduct electricity better than insulator, but not as well as conductors.

• The process of adding of a certain amount of specific impurities atoms in the pure semiconductor.

• when 4 electrons in outermost orbit.

What is diode?

• Electronic device that allow current to flow in reverse biased

• Electronic device that allow current to flow in forward biased

• Electronic device that allow current to flow in one direction only

• Electronic device that allow current to flow in both direction.

Component that Convert AC to DC and allow current to flow in one Direction

• Capacitor

• Diode

• Inverter

• Resistor

Which is a symbol for diode?

• 
• 
• 
• 

Anode is _________ Polarity in diodes

• Negative

• Positive

• Ground

• Hot Side

In the forward bias arrangement of a p-n junction (power) diode,

• the n-end is connected to the positive terminal of the battery

• the p-end is connected to the positive terminal of the battery

• the direction of current is from n-end to p-end in the diode

• the p-end is connected to the negative terminal of the battery

Which diagram shows the correct direction for forward biased?

• 
• 

which statement is correct? (the dark circles represent the electrons)

• p-type of the diode is connected to the negative terminal.

• Electron moves across the p-n junction, makes the diode forward biased

• current will not flow in the circuit

• reverse biased circuit

what is the meaning of rectification?

• a process of smoothing using a capacitor

• a process of adding impurities to pure materials

• a process of converting an alternating current into a direct current by using a diode.
