In the blocked rotor test, the rotor is locked securely enough that it cannot break free. [5] A low voltage is applied on the stator terminals so that there is full load current in the stator winding, and the current, voltage and power input are measured at that point. When the rotor is stationary, the slip, =. [6]
Partials form instead of screw dislocations. Screws which do exist cannot cross-slip across stacking faults, even under high stresses. [14] Five or more slip systems must be active for large deformations to occur because of the absence of cross-slip. For both the <111> and <100> directions there are six and eight different slip systems ...
For low-frequency applications, the power loss can be minimized by employing conductors with a large cross-sectional area, made from low-resistivity metals.With high-frequency currents, the proximity effect and skin effect cause the current to be unevenly distributed across the conductor, increasing its effective resistance, and making loss calculations more difficult.

A piece of cuprate of bismuth and strontium: this piece is a cube with an edge of nearly 1 mm. Bismuth strontium calcium copper oxide (BSCCO, pronounced bisko), is a type of cuprate superconductor having the generalized chemical formula Bi 2 Sr 2 Ca n−1 Cu n O 2n+4+x, with n = 2 being the most commonly studied compound (though n = 1 and n = 3 have also received significant attention).
