1) Compute i2(t) through resist R, Find value of w0 for which the amplitude of the current |I2| is maximum, compute I2 for w=w0. Does I2 depend on R? is there a contradiction with ohm's law?
2) For w=w0, compute the ratio of the amplitude of the voltage source over the amplitude of the voltage across the resistor,
Q=|U|/V0, when V0=sqrt(2), C=8.2microF, L=7mH, and R=1.5kOhms. Is this ratio larger or smaller than one? Explain the apparent contradiction
Design a full wave unregulated dc power supply having an input of 220 V rms 60 Hz and an output voltage maximum of 19.5 V and a minimum of 15 V. This power supply will be needed to provide power to a load which requires a maximum current
Unpolarized light is incident on three polarizers: The first making an angle of 0 degrees with the vertical; the second making an angle of ? degrees with the vertical; and the last one making an angle of 90 degrees with the vertical.
If the work output is 10kW, find the required heat transfer rate from the high to the low temperature source, and the required heat transfer rate to the low temperature source. What is the themal efficiency of the engine
Two transistors, fabricated with the same technology but having different junction areas, when operated at a base-emitter voltage of 0.72 V, have collector currents of 0.2 mA and 12 mA. Find Is for each device.
A single-phase source is connected to an electric load. The load draws a 0.6 oer-unit current at 1.10 per-unit voltage while taking real power of 0.5 per-unit at a lagging power factor. Choose a base voltage of 12.47KV and a current of 100A.
Can you write a part of project which is about developing a schedule of power substation on primavera (P6), focusing on the Changes that will happen based on the following:
