The effect of sweep rate of applied current (dI/dt) on critical current (I c ) of Ag-sheathed Bi 2 Pb x Sr 2-x Ca 2 Cu 3 O y (Ag-Bi-2223) tapes was studied by the four-probe measurement method of V-I curves. It was found that the V-I curves were affected apparently by dI/dt, resulting I c , decrease
