In half wave rectification, if the input frequency is $60 \mathrm{Hz}$, then the output frequency would be

As the temperature increases, the electrical resistance

In the given circuits (a), (b) and (c), the potential drop across the two $p-n$ junctions are equal in:

The truth table for the given logic circuit is:

The electron concentration in an undefined $n$-type semiconductor is the same as hole concentration in a undefined $p$-type semiconductor. An external field (electric) is applied across each of them. Compare the currents in them.

Consider the following statements (A) and (B) and identify the correct answer.

(A) A Zener diode is connected in reverse bias when used as a voltage regulator.
(B) The potential barrier of $\mathrm{p}-\mathrm{n}$ junction lies between $0.1 \mathrm{V}$ to $0.3 \mathrm{V}$.

For the given circuit, the input digital signals are applied at the terminals $A,B$ and $C$. What would be the output at the terminal $y$ ?

An intrinsic semiconductor is converted into $n$-type extrinsic semiconductor by doping it with:-
