= Resistor =
A resistor is a component that introduces resistance that opposes the flow of
current.
A resistor has a set relationship with voltage and current, shown below
V = I * R
== Series and parallel ==
When a resistor is in series, the values add. This means the value will always
increase.
When a resistor is in parallel, the resistance is the reciprocal of the sum of
the reciprocal. This means the values will always decrease. For example, for R1
R2 and R3,
Total = 1/(1/R1 + 1/R2 + 1/R3)
