an amplifier with 40dB of small signal , open circuit voltage gain ,an input resistance of 1 Mega ohm , and an output resistance of 10 ohm , drives a load of100 ohm. What voltage amd power gain (expressed in dB) would u expect with the load connected ? if the amplifier has a peak output currrent limitation of 100mA, what is the rms value of the largest sine wave input for which an undistorted output is possible? what is the corresponding power available?
A turn contains three blue and seven white chips. A chip is selected at random. If the color of the chip selected is white, it is eplaced and two more white chips are added to the urn.
You mix aqueous solutions of sodium iodide and lead(II) acetate. If a reaction occurs, write the balanced molecular equation and the net ionic equation. If no reaction occurs, indicate this by writing the formulas of the compounds and an arrow fol..
