Design a diode voltage regulator to supply 1.5V to a 150-ohm load. Use two diodes specified to have a 0.7-V drop at a current of 10mA. The diodes are to be connected to a +5-V supply through a resistor R. Specify the value of R. What is the diode current with the load connected? What is the increase resulting in the output voltage when the load is disconnected? what change results if the load resistance is reduced to 100 ohms? to 75 ohms? to 50 ohms? (Hint: use the small signal diode model to calculate all changes in output voltage.)
It is desired to use a short-circuited section of a 60-O lossless line to synthesize an input reactance X = - 120 O. If the operating frequency is 1 GHz and the phase velocity on the line is 0.8
Determine the minimun number of 20 Acircuits required to supply the general lighting load in a residence of 1750 sq ft. in terms of good design practice, what is the max of receptacles allowed on a dedicated small appliance branch circuit
A linear circuit has a capacitance of 1.0 mF and an inductor of 1.0 µH. If the frequency response of the voltage gain should stay the same and the capacitor is scaled to 70 µF, what should the value of the inductor be
A perfect conductor joins two ends of a 100 ohm resistor and closed loop is in the region of uniform magnetic flux density B = 10*e^(-t/10) T. Neglecting the self-inductance of the loop, find and plot the voltage V(t)

(b) If the molecular weight of bombykol is 238.4 amu, what is the molecular formula (c) If 5.698 g of bombykol is burned in excess oxygen to form 16.83 g of CO2 and 6.452 g of H2O, how many grams of carbon were present in the original sample
suppose we use a 32-bit unsigned fixed-point representation with the binary point to the left of the most-significant bit of the 32-bit number. (We'll have a range of 0 - almost 1.) What is the resolution of this representation
Describe the characteristics of the series RC filter circuit with the output across the resistive component. Distinguish the pass and stop bands with reference to the cutoff frequency. Also, state what happens to the circuit complex impedance at t..
Selecting a manufaturer from the us and observing wether its annual revenues are more than one billion or not when it is known that 30% of all manufacturers have annual revenues totaling more than one billion dollars.
Find the amount of work required for rearranging a uniformly distributed surface charge Q of radius a into a uniformly distributed volume charge of radius a how can i do this problem in 2 different ways.
In transformer designs, often you can find an air gap in the core. In all the electric machines, there is an air gap between the stator and rotor. In both cases, flux will go through both core material and the air gap.
