The switch of given figure has been open for a long time. It is then closed at t = 0 s.
a. Write the mathematical expression for the current iL and the voltage vL after the switch is closed.
b. Sketch the waveform of iL and vL from initial value to the steady-state level.
design digital ckt. with multiplexer usinggenetic algorithm in matlab for any truth table. its fine for 3variables. problem is how to code for multiplexer part which isincreasing in power of 2.it would be great help if u give some valuable ideas.
A hollow aluminum sphere, with an electrical heater in the center, is used in tests to determine the thermal conductivity of insulating materials.
The surface of the sun has a temperature of 6000 K. Calculate the wavelength at which the sun emits its peak radiancy.
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 10-hp six-pole 60-Hz three-phase induction motor runs at 1160 rpm under full-load conditions. Determine the slip and the frequency of the rotor currents at full load. Also estimate the speed if the load torque drops in half.
A 3-phase induction motor is driving a constant torque load of 1pu at 5% slip. it has a maximum torque of 2 pu at 10% slip. torque-speed variation in stable zone is assumed to be linear. for the stable operation of the motor, the minimum pu supply vo..
It is estimated that youw ill pay about $80,000 into the social security system over your 40-year work span. For simplicity, assume this is an annuity of $2,000 per year, starting with your 26th birthday and continuing through your 65th birthday.
Draw as circuit diagram of the basic non-inverting amplifier configuration. Give an expression for the closed-loop voltage gainof the circuit in terms of the resistances, assuming an ideal co amp
A step-voltage (a voltage obtained when a battery is turned on) is to be amplified. If the rise time of the amplified step voltage is to be less than 2µs (microseconds), find the amplifier bandwidth.
A 15kV:175kV, 125 MVA, 60 Hz single-phase transformer has primary and secondary impedances of 0.0095+j0.063 per unit each. The magnetizing impedances is j148 per unit. All quantities are in per unit on the transformer base.
Several of the voltages associated with certain circuit are given by V12 = 9 phase angle 30 degrees V, V32 = 3 angle 130 degrees V, and V14 - 2 angle 10 degrees V. Determine V21, V13,, V34 and V24
What is the power level entering the first active stage of the receiver at 1900 MHz being fed by a 25 meter coax with a loss of 20 dB/km, given that the Isotropic Receive Level is -134 dBW and the receiving station has a 1 meter radius dish
