Question

A registered engineer is retained as an expert witness by one of in civil case where the public safety is not the parties a case, the involved. In investigating the technical data in the engineer makes findings that are not favorable to the side of the party who retained her. The engineer should A) form the party who retained her of the findings. (B) inform the judge of the findings. (C) inform the opposing party of the findings. (D) say nothing about the findings until called to testify. 24 A registered engineer is retained as an expert witness by one of in civil case where the public safety is not the parties a case, the involved.

Explanation / Answer

Here ,

C = 4 uF

Vc = 1.5 V

Ic = 56.1 mA

a) let the inductance is L

L ( Imax^2) = C * V^2

L * 0.0561^2 = 4 *10^-6 * 1.5^2

solving for L

L = 5.65 *10 ^-4 H

b)frequency of oscillation = 1/(2pi * sqrt(L * C))

frequency of oscillation = 1/(2pi * sqrt(4 *10^-6 * 5.65 *10^-4))

frequency of oscillation = 3348 Hz

c)

time taken = T/4

time taken = 1/(3348 * 4)

time taken = 7.47 *10^-5 s

the time taken is 7.47 *10^-5 s
