The resistor voltage drop equations all take the form
The resistor voltage drop equations all take the form
: <math>\Delta V = IR</math>
: <math>\Delta V = IR</math>
or
or alternately
: <math>V_\alpha - IR = V_\beta</math>.
: <math>V_\alpha - IR = V_\beta</math>.
They describe the voltage drop associated with current crossing a resistor, according to [http://en.wikipedia.org/wiki/Ohm's_law Ohm's Law]. As such, there is one equation per resistor in the circuit.
