The load on a 460-v, 60-Hz, Y-connected, balanced three phase source consists of three equal Y connected impedance of 100-j100 Ohms and three equal delta-connected impedance of 300-j300 Ohms.
1)how would two 50μF capacitors be connected to provide atotal capacitance 100μF. 2) Determine the total capacitance and maximum voltage rating for two 220μF, 300-V capacitors connected in series.
An unpolarized beam of light is sent into a stack of four polarizing sheets, oriented so that the angle between the polarizing directions of adjacent sheets is 50 degrees. What fraction of the incident intensity is transmitted by the system
using a slotted line the following results were obtained distance of first minimum from the load 4 cm distance of
Given an 8kx8 device, you need to create an entire memory system of64Kx16. How do you create it using the 8Kx8 devices and what are the address lines of the 8k and entire system
For loads causing more than 1 V to appear across the generator, the output current is no longer assured but will be reduced by some unknown amount. This circuit limitation, occurring, for example, at the peak of a sine wave signal
When a cloud passes over a certain spot on the surface of the earth a vertical electric field of E = 100 V/m is recorded there. The bottom of the cloud is a height d = 300m above the earth and the top of the cloud is 600m above the ground.
a) By applying Kirchoff's voltage law to the output (DC) circuit loop determine the DC Load Line, i.e. an expression relating Id to Vds. Comment briefly on the significance on the result, with respect to the slope and x-axis intercept.
Given the electric field E= ar (18/r2)(V/m), find the electric potential of point A with respect topoint B where A is at +2m and B is at -4m on the z-axis.
The transfer function of a particular active low pass filter is G(s) = 200/[s(1+0.4s)(1+0.1s)]. a) At a frequency of 1.0Hz it is determined that the gain of this filter in dB b) Find the phase shift in degrees through the filter as the frequency appr..
A communication system must transmit the following real valued signal: v(t) = 4cos(2pi*10MHz*t) + 2cos(2pi*20MHz*t)+cos(2pi*30MHz*t)V For this signal, sketch the positive-frequency power specturm P(f>0)
a). Determine the power this amplifier will deliver to a 4 ohm load, to an 8-ohm load, and to a 1K-ohm load b). What would be the open-circuitvoltage of the amplifier if the signal level were increased
