A resistor&capacitor are in series with a variable inductor.When the circuit is connected to 200v,50Hz supply,the maximum current obtained by varying the inductance is 0.314A.The voltage across capacitor,when the current in circuit is maximum is 800v.Choose the values of series circuit elements?

What is amplitude modulation derive expression for am wave and modulation index?
the maximum amplitude of carrier wave varied with respect to instantaneous values of message signal is called amplitude modulation
What are the advantages and disadvantages of double sideband suppressed carrier modulation?
Amplitude modulation of a carrier results in a transmitted signal consisting of the carrier, plus an 'upper sideband' and a 'lower sideband', spaced above and below the carrier frequency by the frequency of the modulation.The bandwidth of the whole signal is double the modulation frequency. Also, the power in the carrier is constant, and power must be added in order to radiate the sidebands.All the receiver needs in order to extract the information from the signal is one complete sideband, and knowledge of the frequency and phase of the carrier. Economically speaking, the carrier is wasted power, and the other sideband is wasted power andwasted spectrum.If you can filter away one of the sidebands before transmission, then you save half of the occupied spectrum, and the receiver has everything it needs to decode the signal. If you can also filter away the carrier ... or at least knock it way down ... before transmission, you can save a lot of power and use it for the remaining sideband, which extends your range for a given amount of power. The receiver still has everything it needs, as long as it can pick up a sniff of carrier ... enough to derive the carrier frequency and phase.This mode is known as "Single Sideband Suppressed Carrier". It's exactly how the video portion of standard NTSC analog TV was transmitted, throughout all of human history until June 2009.

What is slope overload error in delta modulation derive an expression for it?
: If the input signal amplitude changes fast, the step by-step accumulation process may not catch up with the rate of change of the signal this is called slope overload error

Why you use 12mhz in 8051 micro controller?
Like many early microprocessors it has a 1mhz internal clock for its' operation. 12mhz is divided internally by 12 to derive this frequency.
Why is the period of a pendulum independent of its mass?
As we derive the expression for period using dimensional analysis, we get T = 1/2pi ./(l/g) In this no mass is present. Hence the conclusion
