Resistivity of a Superconductor
... enough to avoid sample heating. Considering the 600 ohm source resistance of the oscillator, the current will be at most, I = V/R = 2 V/600 Ω ~ 3 mA. The fairly high oscillator frequency will ensure that significantly many sine wave cycles will be averaged in a reasonable amount of time. For example ...

... Historically, Ohm showed that the resistance of a metal under constant physical conditions (particularly temperature) is constant. The experiment of passing a varying current through a wire and measuring the voltage across it demonstrates this by generating a straight line graph that passes through ...

Galvanometers
... A galvanometer is an instrument for detecting small currents. It consists essentially of a coil of fine wire mounted so that it can rotate in the field of a permanent magnet. When current flows through the coil, the resulting magnetic force on the coil windings creates a torque on the coil that make ...
