A Building produce 400 V at 200 A. using individual photovoltaic cells that each produce 0.5 V at 1 A . Include a schematic diagram of your design idea.
How many photovoltaic cells are needed for your design?
How much power does each photovoltaic cell produce?
How much power does the Building produce with 400 V at 200 A?
Estimate the number of photovoltaic cells on the Building.
The controlled variable in a closed-loop system is the direction of a robot arm. Initially, it is at 50o; then it is commanded to go to 15o. When the error is 10o for the first time, what is direction of the robot arm
A Si IMPATT diode is operated at 140 GHz with a dc bias of 15 V and an average biasing current 150 mA. (a) If the power conversion efficiency is 25% and the thermal resistance of the diode is 4OoCnV.
A R-C high-pass filter contains a 1 µF capacitor and a 1k resistor. Suppose a single "square" voltage pulse of 5 V for 1 ms duration is applied to the input. Carefully and neatly sketch the resulting output, including numeric values, of output volt..
a 3 V voltage generator is depicted as a thevenin model, the impedence of the generator is represented by a parallel resistor-capacitor combination, the value of the resistor is 20 ohms and the value of the capacitor is 10 farad.
Determine the settings Z1, Z2 & Z3 for the relay at B12.
Find the applied voltage of an iron-core transformer if the secondary voltage is 240 v, and Np = 60 with Ns = 720
In a feedback system, the forward path has a transfer function of the form G(s)=k/(1+s/Omega_p) and the feedback path has a gain of k_fb which is less than unity. Calculate the bandwidth of the closed-loop transfer function
a certain radio frequency generator delivers a power level of 12 dBm. If this signal is amplified, calculate how many decibels of gain is required to produce a power of 20 dBm.
At the end, the wave totally reflects with a pi phase shift, and the reflected wave now interferes with the incident wave to yield a standing wave pattern over the line length.a) Determine the standing wave pattern for the voltage in the line.
A control System with feedback has the following characteristic equation: s3 + (1 + K)s2 + 10s + (5 + 15K) = 0 The parameter K must be positive. When K is equal a single loop of wire with an enclosed area of 0.0900 m^2 is in a region of uniforfm mag..
Consider a Si phtodiode that is designed for operation at 900 nm. GIven a choice of two possible AR coatings, SiO2 with a refractive ndex of 1.4 and TiO2 with a refractive index of 2.3, which would you use and what would be the thickness of the AR..
Write the formula for the maximum clock frequency for an n-bit synchronous parallel binary counter. Beyond what value of n is your formula no longer valid. let Ttq denote the propagatoin delay from T to Q in a T flip-flop.
