Q1. NAND gate output 0 when:
The NAND gate outputs 0 only when both inputs are high (A = B = 1); all other input combinations yield 1.

Physics of Solids MCQs With Explanations
Q2. Rectification device:
A rectifier is a device specifically designed to convert AC to DC by allowing current flow in only one direction.
Q3. Fundamental gate:
The NOT gate is fundamental because it is the simplest logic gate and cannot be constructed from other basic gates.
Q4. NOT gate notation:
The NOT gate inverts the input, represented logically as X = Ā (X equals NOT A).
Q5. DC to AC conversion:
Inversion is the process of converting DC to AC, typically performed by an inverter circuit; 'oscillation' is not a conversion process.
Q6. AC to DC conversion:
Rectification is the process of converting alternating current (AC) to direct current (DC) using diodes or rectifier circuits.
Q7. Silicon barrier potential:
Silicon diodes have a forward bias barrier potential of approximately 0.7 V due to its bandgap energy.
Q8. Reverse current in diode is due to:
Reverse current arises from thermally generated minority carriers drifting across the depletion region.
Q9. Inverter is:
An inverter performs logical negation, which is the exact function of a NOT gate.
Q10. Transistor currents:
In a transistor, emitter current equals the sum of collector and base currents due to conservation of charge.
Chapter 17: Physics of Solids Revision Guide
Complete the MCQs first, then review every incorrect answer against the textbook heading where that concept appears. For biology and other science subjects, pay attention to terminology, diagrams, sequence of processes, examples and differences between similar structures or functions.
This chapter page keeps the exact class, subject, chapter, question count, answer checking, explanations and follow-up chapters together, so students can revise from one focused URL instead of searching through the full book again.
class 12 Physics MCQ Preparation: Physics of Solids
This page supports Intermediate Part 2 practice in Physics. At this stage, the main purpose is consolidating advanced concepts while balancing board revision, college assessments and admission preparation. The questions available here should be used with the current textbook and the instructions issued by the learner's school or examination board.
What Physics MCQs can test
In Physics, objective questions commonly draw on definitions, physical quantities, SI units, laws, graphs, diagrams, formulas and the interpretation of numerical situations. A useful answer is based on the exact wording and concept, not simply on recognising a familiar option. For this subject, learners should write the known quantities and units before choosing a formula, and distinguish a law from the example used to demonstrate it.
Physics of Solids: focused MCQ revision
This chapter should be reviewed through its main definitions, examples, diagrams, comparisons and links with earlier Physics concepts.
Write a one-sentence reason for each corrected answer and note the textbook heading where the concept is explained.
Common mistakes for class 12 learners
In this subject, frequent errors include mixing scalar and vector quantities, overlooking units, reversing cause and effect, or choosing a familiar formula without checking its conditions. Pay special attention to links between earlier intermediate concepts and the more advanced applications introduced in the final year. When the page marks an answer as incorrect, the next step should be to identify the mistaken idea and verify it, rather than memorising the displayed answer letter.
A practical revision routine
Use mixed recall and application questions, then revisit the chapters where formulas, processes or closely related terms are confused. Before attempting the MCQs, review definitions, symbols, unit conversions, graph shapes, diagram labels and the meaning of each term in a formula. Complete a manageable set without notes, check the result, and divide errors into missing knowledge, misunderstood concepts and careless reading. Revise the appropriate section before repeating the chapter.
How to review Physics of Solids after the quiz
List the questions you missed from Physics of Solids and write the textbook heading connected with each one. Explain the correct idea in your own words, then return later and answer a fresh set. This gives the chapter page a clear purpose: finding specific weaknesses in Physics rather than only collecting a score.
Accuracy and responsible use
Explanations are provided where they exist in the question bank, but educational databases can contain incomplete or mistaken material.
