एक p-n जंक्शन डायोड की जंक्शन धारिता (junction capacitance) मुख्य रूप से निम्नलिखित में से किस पैरामीटर पर निर्भर करती है?

A p-n junction is doped with a donor concentration ND and an acceptor concentration NA, resulting in depletion region widths of xn and xp on the n and p sides respectively. According to the charge neutrality condition, choose the correct relationship:

In pure silicon, what is the time required for an electron to drift 1 μm in an electric field of 100 V/cm? (Assume electron mobility is 1350 cm2/V·s)
