Veda Bites are swipeable micro-lessons — each one teaches exactly one idea. Here's a taste from this kit; the app has the full deck.
Zero resistance below a critical temperature.
A superconducting material loses all electrical resistance when cooled below a characteristic critical temperature (T$_c$) — a state no ordinary conductor can reach.
↳ Superconductivity is a distinct state of matter defined by zero resistance below T$_c$.
Two signatures separate superconductors from metals.
↳ Zero resistance and the Meissner effect together define the superconducting state.
Mercury at 4.2 K stunned physicists.
Heike Kamerlingh Onnes discovered superconductivity in mercury in 1911, when its resistance dropped abruptly to zero at about 4.2 K.
↳ Superconductivity was first observed in mercury near absolute zero.
Superconducting materials carry electric current with zero resistance below a critical temperature, and also expel magnetic fields via the Meissner effect. This topic introduces what superconductors are, their defining p...

19 questions laddered from warm-up to topper-level, each with an explanation. A taste:
What is the defining electrical property of a superconductor below its critical temperature?
BeginnerExactly zero electrical resistance
A superconductor has exactly zero resistance below $T_c$, not merely a small resistance.
Which two properties together define the superconducting state?
BeginnerZero resistance and the Meissner effect
Zero resistance and the Meissner effect are the two defining signatures of superconductivity.
The temperature below which a material becomes superconducting is called the:
BeginnerCritical temperature $T_c$
The critical temperature $T_c$ marks the phase transition into the superconducting state.
Which material was the first superconductor discovered, with $T_c \approx 4.2\,\text{K}$?
BeginnerMercury
Mercury was the first superconductor discovered, with $T_c \approx 4.2\,\text{K}$.
