A 16-mH inductor and a 15-mH inductor are connected in series with a 1-A current source. Find (a) the equivalent inductance and (b) the total energy stored.
If there are 500 atoms in the sample and assuming that from any state all possible downward transitions are equally probably, what is the total number of photons that will be emitted when all atoms return to the ground state
design a system comprising a pulley actuated by a stepper motor to lift objects of maximum mass of 1kg. No gear box is required. A 48 VDC power source is available. Select a pulley (specify the diameter) and a stepper motor.
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 second-order bandstop filter is required to satisfy the following specifications: fs= 8,000 Hz f0= 60 Hz bandwidth= 40 Hz Find the transfer function and difference equation by the pole- zero placement method.
The inductance of an air core coil is 0.08H, and the effective resistance is 4 ohms when a 60V, 50Hz source is connected across the coil. Find the current passing through the coil and the reading of a watt meter across the coil.
Under steady operating conditions, cold water at 15 oC and 200 kPa enters the water heater with a flow rate of 54 kg/min and leaves the water heater at 80 oC and 200 kPa. During its operation the water heater loses heat to its surroundings at the ..

1. How would you bias a BJT in a common emitter amplifier in order to minimize the Miller feedback capacitance 2. Explain how it is possible to identify the different current transport mechanisms.
A Series RLC with R = 50Ω and C = 32nF is connected to anideal 5 V voltage source, and is observed to be resonant at ω= 50x103 s-1. a. Draw and label the circuit diagram. Show all voltage andcurrent references.
The value of Q is 1 and only if the number of clock ticks (after reset) is either a multiple of 2 or a multiple of 3. Otherwise, the value of Q is 0. Draw a state diagram for the machine using as few states as possible (Hint: More than three state..
Rain harvesting is a means of water conservation. This real-life problem requires computation and critical thinking involving a practical solution. Apply the problem solving approach studied in class to this rain harvesting and irrigation problem.
