The time average power density of radiation from the sun at the surface of the Earth is about 1550 W/m^2.
a) How much total power is incident on the state of Colorado on a sunny day. Compare this to the average electrical energy consumption of the United States which is on the order of 10^12 Watts.
b) Find the peak electric and magnetic fields of solar radiation.
c)If the radius of the Earth is 6.37Mm (1Mm = 10^6m), the radius of the sun is 700Mm, and the radius of the Earth's orbit around the sun is 1.5x10^8 km, find how much total power the sun emits in Watts.
d) Calculate the force felt by a car with surface area of 1.5 m^2 (Hint: this is a radiation pressure problem, Pressure = ((power flux density)/C)
1) For a forwarard converter, derive the minimum value of Vr - as a function of the input voltage Vg, the duty cycle D, and the turns ratio N1/N2 - that will cause the transformer magnetizing current to be reset to zero by the end of the switching..
A candidate material for a turbine blade application oxidizes by diffusion of metal atoms through the oxide to the metal surface, where metal and oxygen react to form the oxide. After 10 hours at 550*C, an oxide layer 8µm thick has formed.
An input signal of 10V at 0o is applied to a parallel RLC circuit with resistor R = 10 , inductive reactance XL = 20 , and a capacitive reactance XC = 10 . All three components are connected in parallel to the source.
A load has a 20 ohm resistor and a 4 Henry inductor connected in series. It is connected to a power source with v(t) = 100 cos(50t), connected in series to the load. What is the impedance of the load? Use phasor transform methods to obtain your an..
The NF (dB) is defined as 10log(SNRin/SNRout) - in the unit of dB. If we are given the values of SNRin and SNRout in dB unit, how do we calculate NF (dB) in terms of dB, and how do we calculate NF in term of a pure ratio
Finding peak amplitude, frequency, and spectrum shape, b. A signal generator outputs a unipolar square wave with a period of 0.50 ms and an amplitude of 2.0 V. The output of the generator is passed through an ideal band pass filter that has a pass..
Design a circuit to give uninterrupted 5 V dc power supply with 110 V 60 Hz line voltage as input. The dc output should be available in case of power outage (110 V line supply). In case of line failure, the circuit should switch to backup source t..
Knowledge about Circuit Analysis, A 5.1K resistor is connected between the cathode of a 6.2V zener diode and a 12V power supply
An air-standard Otto cycle has a compression ration of 9. At the beggining of compression, p1=100 kPa and T1= 300K. The heat addition per unit mass of air is 1350kJ/Kg. Determine. a) the net work, in kJ of air. b) the thermal efficiency of the cyc..
Three loads are connected in parallel across a single-phase source voltage of 240 V (RMS). Load 1 absorbs 12 kW and 6.667 kVAR; Load 2 absorbs 4 kVA at 0.96PF leading; Load 3 absorbs 15 kW at unity power factor.
Estimate the size and weight of an 1970 automobile using 1970 electronics technology which would have the equivalent computational power and electronics a typical 2013 automobile.
A CG amplifier when fed with a signal source having Rsig = 200 ohms is found to have an overall voltage gain of 10V/V. When a 200 ohm resistance is added in series with the signal generator the overall voltage gain decreased to 8V/V.
