There are (3) devices here of which (2) are frequency dependant; the capacitor and the inductor. The capacative reactance Xc = 1 / (2 * pi * Freq * C ) = 1 / (2 * pi * 10E6 * 820E-12) = 194.0914 ohms or -j194.0914 as a phasor. The...

The Formula is: Q = C x U (Q in Coulomb) so a) charge Q = 100 x 12 = 1200 picoCoulombs = 1.2 micro-Coulombs The potential difference V = q/C requires the work dW = dV...

1) We have a linear relationship between the two quantities. Since it doesn't go through the line it has an offset or a bias from direct proportionality. 2) We have a situation where the change of a quantity is directly proportional to the change of the other. y = mx, then y is directly...
