Think of a monomer as being a brick, and a polymer, or macromolecule, as being the whole brick wall composed of the building blocks. The brick wall is composed of smaller units-the bricks-just as a macromolecule is composed of monomer building blocks.heck out the table below for some examples of proteins in your body. Lipids are macromolecules that are made up of long chains of fatty acids, or carbon rings. Important lipids in your body include cholesterol, steroid hormones, triglycerides, and phospholipids.
Current, voltage and resistance are related by the Ohm's law formula which states that current is directly proportional to the applied voltage and inversely proportional to th â¦ e resistance at a constant temperature.
Note that the current density is often not constant, so a weighted summation (Equation [1]) is needed. Finally, suppose a medium (material) has an electric conductivity given by (which is measured in Siemens/meter, which is the oppose (inverse) of resistance per length).n Equation [3], the E-field is analogous to voltage, current density is analogous to current, and the conductivity is the inverse of resistance. This is where Ohm's Law for circuits comes from. Equation [3] states that in a material with a non-zero conductivity, an E-field will produce an electric current.
