What is the critical temperature in superconductivity?

Last Updated: 25 Jun 2026

What is the critical temperature in superconductivity? Here, the relevant answer is “Temperature below which resistance becomes zero.” A sound solution relies on the governing concept rather than a memorised option letter, because option order may change in another paper. The distractors in this question—Temperature above which conductivity increases, Temperature of absolute zero, Temperature at which conductivity decreases—do not satisfy the exact condition stated. The final selection must agree with the explanation and marked answer: Temperature below which resistance becomes zero.

ATemperature above which conductivity increases

BTemperature below which resistance becomes zero

CTemperature of absolute zero

DTemperature at which conductivity decreases

Correct Answer: Temperature below which resistance becomes zeroYour Answer: B

Explanation

— the scientifically appropriate response is Temperature below which resistance becomes zero. Option-wise review: Temperature below which resistance becomes zero is correct under the condition given in the stem. Temperature above which conductivity increases is incorrect because it describes a different quantity or phenomenon and does not meet the stated condition. Temperature of absolute zero is also incorrect; although it may be a valid physics term, its definition or application is not the one asked here. Temperature at which conductivity decreases is incorrect because it fails the governing relation or characteristic relevant to this case. Therefore, option B, Temperature below which resistance becomes zero, is factually and logically consistent with the question. Critical temperature is the temperature below which a material becomes a superconductor with zero electrical resistance.

Important Notes

Read the complete stem before looking at the options. Identify whether the demand is a definition, unit, formula, direction, cause, effect, image characteristic, or device principle. In this record, the confirmed answer is Temperature below which resistance becomes zero.
Physics answers are condition-dependent. The same lens, force, circuit, wave, or thermodynamic system can behave differently when distance, medium, temperature, direction, or boundary conditions change. Preserve every qualifier in the question.
Do not interchange closely related terms: mass and weight; distance and displacement; speed and velocity; heat and temperature; reflection and refraction; real and virtual image; current and potential difference; power and energy. Such pairs generate common SSC distractors.
Eliminate Temperature above which conductivity increases, Temperature of absolute zero, Temperature at which conductivity decreases here because none fulfils the exact requirement of the stem. The final answer and correct-index field must point to option B.
Exam memory point: connect Temperature below which resistance becomes zero directly with the key wording of the question, then verify it once against the relevant definition or formula before marking the answer.Discovered by Kamerlingh Onnes

FAQ

SSC CGL Physics FAQs

Common questions and clear answers for this topic.

How many physics questions usually appear in the SSC CGL exam?

Physics typically makes up a small portion of the General Science questions, usually focused on concepts rather than numerical problems.

Which physics topics are most important for SSC CGL?

Basic mechanics, heat, sound and light, and electricity and magnetism are the areas that come up most consistently across previous papers.

Do I need to solve numerical problems for SSC CGL physics?

Rarely. Most questions are conceptual and test everyday understanding rather than calculation skills.

Is NCERT physics enough for SSC CGL preparation?

NCERT textbooks from classes 9 and 10 build a strong enough conceptual base for most of what SSC CGL asks.

How can I make physics concepts easier to remember for SSC CGL?

Connecting concepts to everyday observations, like why a thermos keeps tea warm, makes them far easier to recall than memorizing definitions.
