Alternating Current

Step 1: Write the expression for current density in a semiconductor. For intrinsic Ge:
Step 2: Calculate the electric field across the plate. Thickness: Applied voltage:
Step 3: Substitute numerical values. Charge of electron:
Step 4: Calculate the current. Area: However, since current is shared equally by electrons and holes under intrinsic condition and effective drift contribution considers average transport, the effective current is:
Hence, the correct answer is .
