Basic DC Circuit Calculations Summary
Equivalent resistance is a term used to represent the total resistance a
combination of loads presents to a circuit.
A voltage divider is used to obtain different values of voltage from a single
energy source.
Current division is used to determine the current flowing through each leg of
a parallel circuit.
