Voltage, where V = IR, is the product of the current ( I ) of Amperes in an electrical circuit in units of coulombs per second ( q/s ), and resistance ( R ) in Ohms. Likewise, voltage is defined as the amount of energy in Joules ( J ) a coulomb of charge carriesContinue reading “ELECTRICITY: Kirchhoff’s Rules and Negative Current Values”

HEAT AND THERMAL ENERGY: Thermal Expansion of Solids and Liquids.
The subatomic structure of solids and liquids have a profound influence upon how they react to a transfer of thermal energy. Solids have a relatively fixed or rigid structure, whereas the molecular structure of liquids allows for greater expansion and compression. Measurements have shown that ( in general ) a linear relationship exists between theContinue reading “HEAT AND THERMAL ENERGY: Thermal Expansion of Solids and Liquids.”
