Asked in MDCAT Test Series 29 — ElectronicsModerate

Statement: Despite the Principal's repeated warnings, a child was caught secretly exploding crackers in the school. Courses of action:I. All the crackers should be taken away from the child and he should be threatened not to do it again.II. The child should be severely punished for his wrong act.

Correct answer: B. If only II is most appropriate

  • A. If only I is most appropriate
  • B. If only II is most appropriate
  • C. If either I or II is most appropriate
  • D. If neither I nor II is most appropriate

Explanation

The child has already ignored "repeated warnings," so another threat (Action I) is unlikely to be effective. The situation has escalated to a point where a more significant disciplinary action (punishment) is required to address the deliberate and repeated defiance of safety rules.

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.
