Consider the probability density f(x) = ae^-b|x| where x is a random variable whose allowable values range from x = - ∞ to x = + ∞. The Cdf (Cumulative distribution function) for x ≥ 0 is :

The electric field of uniform plane wave is given by E = 20 sin (2 p x 10⁸t- pz) _x + 20 cos (2 p x 10⁸t - pz) _y. The corresponding magnetic field is

Find I for circuit shown below

A n-type silicon sample contains a donor concentration of N_d = 2 x 10¹⁶ cm^-3. The minority carrier hole lifetime is t_p0 = 5 μs. The thermal equilibrium generation rate of hole is:
