Testing Resistor



                   There are two ways of testing resistor; using an analogue or digital
                   multimeter. Normally if a resistor fails they will either increase in
                   value or open up at all (open circuit). You can check the resistor
                   resistance by selecting the ohmmeter range in the analogue and digital
                   multimeter. If the resistor is in circuit, you will generally have to remove
                   the resistor so you are testing only the resistor value and not the other
                   components in the circuit. Always be aware of possible back (parallel
                   circuit) circuits when checking in-circuit resistance measurements.
