1. Let Vi has a peak of 10v and R=1kOhm. Find the peak value of id and DC compoent V-o.2. Consider a silicon diode with n = 1.5 Find the change in voltage if the current changes from 0.1 mA to 10 mA.3. A silicon junction diode with n = 1 has v = 0.7 V at i = 1 mA. Find the voltage drop at i = 0.1 mA and i = 10 mA.4. Find the value of the diode small-signal resistance r_d at bias currents of 0.1 mA, 1 mA, and 10 mA. Assume n = 1.
An induction motor takes 350kW at 0.8 power factor lagging while driving a load. When an overexcited synchronous motor taking 150kW is connected in parallel with the induction motor, the overall power factor is improved to 0.95 lagging.
If she is a carrier, then each prince has a 50-50 chance of having hemophilia, independently of the other princes. If the queen is not a carrier, the prince will not have the disease. Suppose the queen has had three princes, each without the disea..
The signal x(t)=10cos(t)+10sin(10t) is input into the following systems: a) \(H(s)=100/(s^{2}+10s+100)\) b) \(H(s)=s^{2}/(s^{2}+10s+100)\) calculate the output for each system.
Wires manufactured for use in a computer system are specified to hve resistances between .12 and .14 ohms. The actual measured resistances of the wires produced by company A have a normal probability distribution with mean .11 ohm
a) Design a minimum two-level NOR-gate network to realize the above function. b) Design a minimum three-level NOR-gate network to realize the above function.
Draw a circuit model of the path of current through the human body for a person touching a voltage source with both hands who has both feet at the same potential as the negative terminal of the voltage source.
Explain the relationship between the input and the output ac signals for a n-channel BJT voltage-divider bias. What components/parameters does the voltage gain depends on
An EEG signal from a healthy adult contains clinically relevant frequencies in the range of 0 to 45 Hz. The frequency bands are generally grouped as delta (0.5-4 Hz), theta (4.5-8 Hz), alpha (8.5-13 Hz), and gamma (30-45 Hz).
The turns ratio (n3/n1) is chosen such that the converter produces the required output voltage at a transformer duty cycle of D=0.4. For each case determine numerical values for the turns ratio n3/n1 and for the efficiency.
An OFDM system with a passband bandwidth of 10 MHz and carrier frequency of 1 GHz is used in an outdoor environment with a maximum delay spread of 15 microseconds.
150 kVA, 2400/240 V single-phase transformer has the parameters. (a) Determine the equivalent circuit referred to the high-voltage side. (b) Find the primary voltage and voltage regulation when transformer is operating
A bus in a balanced three-phase power system has a three-phase capacitor bank that supplies 1200 kVAR. In parallel with the capacitor bank is a three-phase load that draws 3500 kW at a power factor of 0.707 lagging.
