Carbohydrates have the general molecular formula CH 2 O, and thus were once thought to represent hydrated carbon. However, the arrangement of atoms in carbohydrates has little to do with water molecules. Starch and cellulose are two common carbohydrates.Both are macromolecules with molecular weights in the hundreds of thousands. Both are polymers (hence  polysaccharides ); that is, each is built from repeating units, monomers, much as a chain is built from its links.The monomers of both starch and cellulose are the same: units of the sugar glucose.hey are: 1  glucose, blood sugar, the immediate source of energy for cellular respiration. 2  galactose, a sugar in milk (and yogurt), and. 3  fructose, a sugar found in honey.
In a typical electret condenser microphone, it is the JFET that requires unbalanced bias and the preamplifier that requires balanced phantom power. This means that a condenser microphone requiring phantom power will not work with an input that only supplies bias, e.g. a wireless transmitter.
The condenser microphone is built with an amplifier attached to it. The amplifier is required to operate this type of microphone. A very low-noise, high-impedance amplifier is used and it provides a low output impedance. Without the amplifier, the microphone's output signal would be so low, it wouldn't be useful. condenser microphone needs to receive an external voltage to both charge the diaphragm of the microphone so that the microphone can have charged plates (positive and negative plates) and to provide power to the amplifier.
