The ratio of electron and hole currents in a semiconductor is 7/4 and the ratio of drift velocities of electrons and holes is 5/4, then the ratio of concentrations of electrons and holes will be

The ratio of electron and hole current in a semiconductor is (7)/(5) and the ratio of drift velocities electrons and holes is (1)/(4) ,then the ratio of concentrations of electrons and holes will be ?

How are electron-hole pairs created in a semiconductor?

The contribution in the total current flowing through a semiconductor due to electrons and holes are 3/4 and 1/4 respectively. If the drift velocity of electrons is 5/2 times that of holes at this temperature, then the ratio of concentration of electrons and holes is

The contribution in the total current flowing through a semiconductor due to electrons and holes are 3/4 and 1/4 respectively. If the drift velocity of electrons is 5/2 times that of holes at this temperature, then the ratio of concentration of electrons and holes is

The contribution in the total current flowing through a semiconductor due to electrons and holes are 3/ 5 and 2/ 5 respectively. If the drift velocity of electrons is 2 times that of holes at this temperature, then the ratio of concentration of electrons and holes is
