Question:medium
In a semiconductor, \(\frac{2}{3}\)rd of the total current is carried by electrons and remaining \(\frac{1}{3}\)rd by holes. If at this temperature, the drift velocity of electrons is 3 times that of holes, the ratio of number density of electrons to that of holes is
In a semiconductor, \(\frac{2}{3}\)rd of the total current is carried by electrons and remaining \(\frac{1}{3}\)rd by holes. If at this temperature, the drift velocity of electrons is 3 times that of holes, the ratio of number density of electrons to that of holes is
Show Hint
Current ratio depends on number density × drift velocity.
