A constant area fin of length and cross-sectional area generates heat at a volumetric rate 2L Ac qc. Half the fin is insulated while the other half exchanges heat by convection.
The heat transfer coefficient is h and the ambient temperature is The base and tip are insulated. Determine the steady state temperature at the midsection. At what location is the temperature highest?
A signals values have a range of +- 5V and you wish to make measurements with an analog quantization size no mate thatn 5mV. What minimum resolution A/D converter is required to perform this risk
if the shaft load remains fixed, but the field flux is reduced to 70% of its value by field control, determine the new operating speed.
determine the following. (a) The line current (b) The value of the capacitor in uf per phase, is a wye-connected capacitor bank is used to correct the power factor to a 0.95 lagging power factor.
Design a voltage regulator circuit that can provide a voltage Vload = 5V at a maximum of 100mA from a 6-V battery. A maximum of 1 W of power should be dissipated in any one component.
If this machine is operating at rated conditions, what input torque must be applied to the shaft of this generator? Express your answer both in newton-meters and in pound-feet.
An analog system requires an antenna signal power of 100pW to meet the required detected signal-to-noise ratio. Other system parameters are given as follows: Gt(dB) =4dB determine the minimum value of the transmitter power required.
The rotor winding consists of 55 turns per pole with a winding factor ofKr=0.89. The peak value of a fundamental air-gap flux densityis limited to 1.0T and the rotor winding current to 2900A.C
Starting from Ampere's law, calculate the self inductance of the coil, assuming that the cross sectional area of the coil is sufficiently small that we can assume that the magnetic field has constant strength inside the coil.
The lighting and motor loads of a small factory establish a 10kVA power demand at 0.7 lagging power factor on a 208V, 60 Hz supply. Determine the power-factor capacitor that must be placed in parallel
An IC NMOS transistor has W=100μm, L = 10μm,μnCox= 20μA/V2, VA= 100 V, γ = 1/2 V1/2, Vt0= 1V, and 2φf= 0.6V. calculate the value of Vt at VSB= 4V. Also for VGS=3V and VDS=5V, Calculate ID for VSD = 0V and for VSB = 4V
Problem: This semester you will realize a Moore finite state machine for implementing the tail lights of a prototype car using four different design tools:
While an inductor is being energized the current flowing through it as a function of time is: i(t) = 56 (1 - e(-4600 · t) ) mA, for all times t > 0 and t is in seconds. What is the inductance, if a voltage drop of 1.188 V is measured across this indu..
