Introduction to Basic Electronics and Digital Electronics Quiz

Electricity and Electronics

• The fundamental field that has revolutionized the way we live is Electricity and Electronics.

Electrical Circuits

• The component that controls the flow of electric current in an electrical circuit is a resistor.

Semiconductor Diodes

• The semiconductor type that forms the P-N Junction Diode is P-type and N-type semiconductors.

Rectifiers

• The bridge rectifier has the highest efficiency among the listed options.

Bipolar Transistors

• The two types of bipolar transistors are N-P-N (Negative-Positive-Negative) and P-N-P (Positive-Negative-Positive) transistors.

Transistor Structure

• The impurity used for realizing the base region of a silicon N-P-N transistor is P-type (positive-type) semiconductor.

P-N Diodes

• In case of forward bias, the p-n junction diode acts as a closed switch and conducts current.

Junction Transistors

• Electron-hole recombination occurs in the depletion region of a junction transistor.

Semiconductor Properties

• The bandgap of Germanium at room temperature is 0.67 eV (electronvolts).

Zener Diodes

• The correct biasing of a Zener diode when used in voltage stabilization circuits is reverse bias.
