[電磁] 98台聯大物理 第20題答案
98台聯大物理第20題是在問有關超導體的題目
20.which one of the following statement of superconductor is wrong?
(A)the resistivity goes to zero.
(B)when temperature increases higher than its critical temperature,
the superconductivity will disappear.
(C)the electric field inside a superconductor must be zero.
(D)the magnetic field inside a superconductor must be zero.
(E)the conductivity goes to infinity.
題目是要求選出錯的敘述
台聯大公布之解答為(C)
我選(D) 因為我想說超導體也算是導體 而導體內電場為零
想請教各位大大 到底是C錯還是D錯 @@"
