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
The power supplied by a certain source is a constant 7.5 W over the first 5.8 min, zero for the next 2.8 min, a value that increases linearly from zero to 10 W during the next 8.8 min, and a value that decreases linearly from 10 W to zero
An amplifier with a voltage gain of +30db, an input resistance of 8 k ohms, and an output resistance of 2 k ohms is used to drive a 2 k
