Tricks of the
trade
If you happen to
have several resistors on hand or are unable to find the
impedance (resistance) value, different resistance value can
be "created" by adding resistors in series or parallel.
Both of the
configurations will provide different resistant and current
rating values. |
|
Example:
-
If your
vehicle requires a 200ohm resister you can wire two
100ohm resistors in series to achieve a 200ohm resister,
the current capabilities will stay the same as if they
were on. However, in most cases using resistors in the
data bus driving application the current rating
requirement of the of the resistor is minimal and will
not be a concern.
-
Lets take the
same example with the 200 ohm resistant required to
activate your vehicle door lock. You can take two 400ohm
resistors and wire them in parallel to achieve a 200ohm
resister. The current capacity will double.
