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

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
|
2022-01-26 19:00:01 +00:00
|
|
|
the reciprocal. This means the values will always decrease. For example, for R1

|
R2 and R3,
|
|
|
|
|
|
|
|
|
|
Total = 1/(1/R1 + 1/R2 + 1/R3)
