many cell phone battery chargers operate on 2.4 volts, while others operate on 3.0 volts. The cell phone battery charger in use for this project is 2.4 volts , but it is broken and cannot charger the battery . you do, however , have available a 3.0 volt charger.design the necessary circuitry using only resistor and diodes to enable the charging of the battery. as a simplifying assumption you may treat the battery current as negligible. if you choose to use more then one diode in the design assume that you have identical didoes.once the circuit is designed and simulated determine the reverse saturation current for the diodes ot diodes in use.determine the power consumption for each of hte elements in the design.
Dispense requested amount using least number of bills, Write a C program for an automatic teller machine that dispenses money. The user should enter the amount desired (a multiple of 10 dollars)
HCI is a polar molecule, with a dipole moment of 3.44 X 10^-30 [C.m] per molecule. If it is known that the molecular bond distance is 0.136[nm], find the magnitude of the net displaced charge in each molecule.
A three-phase 600VAC generator delivers 2000KVA at a lagging power factor of 81%. If the generator is 86% efficient how much horsepower is required to operate it If the generator outputs its rated voltage what would the line current
An object in a microwave oven 25 cm in diameter and 4 cm thick is being warmed. Determine how deeply the signal penetrates if the objects εr is 12.5 and σ is 2 S/m at a frequency of 2.5 GHz. Assume that the plane wave calculations are valid.
A charged 100-pf capacitor has initial voltage across it of 10V. a 100kohm resistor is suddenly connected across the capacitor (at t=0) to discharge it. What is the magnitude of the instantaneous current at 20 usec?
If I want to stream audio data over a digital data link how much channel capacity is required for stereo 16 bit audio sampled at 44kHz. How does this rate compare to common rates for MP3 formatted audio files.
An npn transistor of a type whose P is specified to range from 60 to 300 is connected in a circuit with emitter grounded, collector at +9 V, and a current of 50 pA injected into the base.
A current amplifier with R=9 kohm Ro=1 kohm and Ais=100 is connected between a 8 V voltage source with a source resistance of Rs=1 Kohm and a load resistance of RL=9 Kohm.
Write a three function program. The main function must create a string array with room for 10 elements. The main function should call the second function passing it the array as the first argument and the size of the array as the second argument.
The unknown input impedance of a horn antenna operated at a frequency of 300MHz is measured using a slotted transmission line and a Smith Chart. When the antenna is connected to the slotted line, the VSWR on the line is measured to be 4
Draw a logic diagram of simple logic that converts the control variables CA, CB, and CC as inputs to outputs that are the SELECT inputs for the multiplexers and LOAD signals for the registers.
A 3-phase, 440VAC, 6-pole, 60Hz, wye connected induction motor takes 30KVA at .8 power factor lagging, and runs at a slip of 3.5% at full load. The stator copper losses are 500W, and the rotational losses are 350W.
