determine the current through the capacitor, i_c(t) for time t greater than or equal to zero if the following statements apply.
1. Vc(t=0) = 5V
2. The switch is closed from t = - infinity to t = 0.2 seconds, when it opens.
3. u(t) is the unit step function
4. u(t - 0.2) is the unit step function with time delay 0.2 seconds
A uniform electric field of magnitude 690 N/C exists between two parallel plates that are 3.88 cm apart. A proton is released from rest at the positive plate at the same instant an electron is released from rest at the negative plate.
A platinum resistance coil has a resistance at O0 C of 100 . Determine the change in resistance that will occur when the temperature rises to 30°C if the temperature coefficient of resistance is 0.0039 K-1.
What is the purpose of a state diagram, and what information can we derive from it. What is the major differences between an asynchronous counter/divider and a synchronous one.
A bar phantom is imaged by an LSI system which is modeled as an ideal moving average system. The PSF of the system is h(x,y) = rect(x/delta, y/delta) (a) If bar separation of the bar phantom is f what is the output of the imaging system
Referring to the circuit with switches connected to doors: Consider 3 doors, Doors A, B, and C. Design a circuit that will illuminate an LED only if both Doors A and B are closed or if Door A is closed and Door C is open.
Given R = 50Kohm and C = 100nF what is the frequency of oscillation Given a required frequency of oscillation of f = 10kHz and R = 8kohm, what should the value of C be
A 150MW alternator generates an open-circut line-t0-line voltage of 12kV at nomial DC excitiation. When the terminals are placed in short-circuit the resulting current per phase is 8000A. a) Calculate the approximate value of the synchronous reacta..
A three-phase, 400 V system has the following load connected in delta: between the red and yellow lines, a non-reactive resistor of 100; between the yellow and blue lines, a coil having a reactance of 60 and negligible resistance
how to evaluate power dissipated in the components of an RLC series circuit by using matlab software?
Determine the minimum signal to noise ratio (s/n) in dB required in each communication channel to achieve a data rate of 270 kbps?
design a circuit to sort a product which has 2 different color in two diffrenet boxes for example red and green apples no any microcontroller or microprossser are allowed. which color sensor is the best to have 5 volt output so a solenoid may work..
