P. 4549. A thyristor is an electrical element made of semiconductor, and can be used in many different ways. Its current-voltage characteristics is quite strange. (See figure 1.)
The thyristor is connected as shown in figure 2, and the voltage U0 is slowly increased from zero to Umax , and then it is slowly decreased back to zero.
Graph the current as a function of the voltage U0, if
a) and ,
b) and .
