Ohm’s Law – 9 minutes
Names the electrical quantities represented by I, E, and R. States Ohm’s law in words and as a formula. Shows how to calculate the current, voltage, or resistance of a simple circuit when any two of the quantities are known. Presents a memory aid.
Series Circuits – 10 minutes
Describes how to calculate: total resistance of a series circuit when its individual series resistances are known; resistance of a single series component when the total circuit resistance and the remaining series resistances are known. States Kirchhoff’s voltage law, and shows how to calculate the voltage drops across each component in a series circuit.
Parallel Circuits – 12 minutes
States Kirchhoff’s current law. How to calculate the branch currents in a parallel circuit when the source voltage and the individual branch resistances are known, the total current through a parallel circuit when the individual branch currents are known, and the total resistance of a parallel circuit when the individual branch resistances are known.
