A plane of orange light polarized with an electric field amplitude 3x10-4 V/m in the x-direction, is traveling through vacuum in the positive z-direction.(a) Write an equation describing the electric field in complex exponential form, with all known quantities expressed numerically.(b) Part of the wave enters an ideal dielectric with e = fo*er = 4 x 10-11 F/m. Calculate the wavelength, wave number, frequency, angular frequency, and velocity of this orange light within the dielectric. Assume the material to be nonmagnetic.(c) Part of the same wave enters a conductor with a conductivity of 104 S/cm. Calculate the skin depth. By how much will the electric field of this wave be attenuated in traveling through
A sinusoidal voltage has a maximum value of 100V, and the value is 10V at t=0. The period is T=1ms. Determine the angular frequency, w, in rad/sec.
How much stator referred „external? resistance per phase should be connected in the rotor
Find the largest allowable signal swing (peak-to-peak) at the collector to satisfy the two conditions: BJT remains active , and vbe limited to 5 mV . What is the corresponding allowable peak-to-peak input voltage vi
Design a circuit to provided a positive voltage whose magnitude is equal to the acceleration (revolutions pre minute) of the wheel. Assume the velocity sensor's output 1 mV/rpm, and the wheel rotates at less than 3500rpm.
At a substation the primary of a step-down transformer (turns ratio = 1:26) receives the voltage from the high-voltage transmission line. Because of your usage, a current of 48.0 mA exists in the primary of this transformer.
Bode plots were introduced in my second circuit analysis class, but I really didn't think it was important because it looked like an outdated tool no longer in use.
