When p-type and N-type semiconductor are combined then we have a:
Correct answer: C. Diode
- A. Resistor
- B. Capacitor
- C. Diode
- D. Triode
Explanation
When P-type and N-type semiconductors are combined, they form a PN junction, which is the fundamental building block of a diode. This junction allows current to flow primarily in one direction, which is the defining characteristic of a diode. A resistor, capacitor, and triode are different types of electronic components with distinct functions and are not formed by combining P-type and N-type semiconductors. Resistors oppose current flow, capacitors store electrical energy, and triodes are vacuum tubes used to amplify signals.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
