Question 4

Continuous Time Fourier transform does not exist for

Question 5

3 parallel wires a, b, c carry charges +2q, –q, –q per unit length respectively. Points in the field are specified by the distances r₁, r₂, r₃ from the three wires. Equation for the equipotential surface is given by.

Question 6

It is given that A is a real skew − symmetric matrix having order 3. Which of the following set denotes the eigenvalue of A?

Question 7

A pure Ge sample has intrinsic carrier concentration of ղ_i =2.5 x 10¹³ cm^-3 mobility of electron and holes are 3800 cm²/ V-sec and 1800 cm²/ V-sec respectively. Then the required donor impurity concentration should be added to Ge sample so that its resistivity drops to 15% of its original value is (Assume minority carrier concentration is negligible after adding donor impurities.)

Question 8

From the following figure, the voltage across the 3µF capacitor at t = 0^- and t = ∞ is___
