Continuity is checking for a completed circuit including a short circuit. Checking resistance would be checking in ohms resistance of a circuit, motor windings or an open circuit.
You open one of the leads of resistor connected in electronic circuit while measuring its resistance in order to not introduce error cause by other components in the circuit.

It measures resistance in a component or circuit to determine if there is a break in that circuit or component. If there's no resistance, it means there's a break, as no electrical current is passing through.
Firstly turn of the power before this test...Using a resistance or continuity tester you should get the following results:Short circuit: Very low resistance (nearly 0 ohms) or the bell will ring.Open circuit: Very high resistance (Somewhere in the range of Mega ohms) or the bell will not ring.The reason for this is because and open circuit has a gap in it (which has high resistance).The short circuit has wires that are crossed and so has a really low resistance.
An electronic circuit is a network of interconnected electronic components composed of one or more loops coupled that is designed to perform some useful function. The major difference between an electronic circuit and an electrical circuit is that the electronic circuit contains active components that can amplify and/or switch signals and/or nonlinear components that modify signal shapes, while electrical circuits contain only passive linear components in most cases.
Resistors are one of the three basic electronic components. They restrict the flow of current in an electrical circuit. Fixed resistors have a fixed value of resistance, and are used in almost every electronic circuit for lots of different reasons.
If measuring resistance of materials or resistors by themselves(not soldered into a circuit board) resistance is constant. If measuring resistance of a circuit then it could fluctuate with the components functioning in the circuit.
