The Purpose of the Resistor

This is probably the most basic component of all existing electronic components and as the name already implies the main characteristic of this component is resistance. It restricts current flow, higher resistivity value means lower current flow through the resistor and bigger voltage drop across the resistor. When this is placed inside the control panel instead of at the end of the line (EOL) it has been installed incorrectly. This component helps create integrity on the line in the case that there is a fault.

When reading the resistors value while the resistor is part of the electrical circuit, the Digital Multi Meter may not be possible. The reading won't be accurate because other components may be affecting the results. If you need to know the value of resistance for a replacement component please see chart below.
