You almost NEVER do. 1) The circuit should be off and/or disconnected when using an ohmmeter. 2) It should be in parallel with the component as far as the rest of the circuit is concerned, but alone in series with the device its measuring.
Turn off the supply before using the ohmmeter,it will damaged your ohmmeter when supply is present.
By connecting it to a circuit with the power still applied. Ohm meters work best when the component under test is removed from the circuit to eliminate parallel paths of current through other components.
ANY METER needs some kind of current flow to operate. Internal in the meter there are batteries that provide current that when passed trough a resistor will develop voltage as a function of the current. the meter will read this current and display the resistor size to cause this current to flow.
Ghost power may be acting on a circuit if it has a capacitor or transformer connected. This will supply power long after the input has been disconnected.

An ohmmeter is connected in parallel to a resistor. Be sure that there is no power in the circuit when testing.
An Ohmmeter.

This is false. A zero reading is what you get when you press the probes of themeter together with nothing between them, to make sure the meter is working.That's about as closed as the circuit under test can get.
When a multimeter is connected across an open component, the multimeter will display an infinite or overload reading. This indicates that there is no electrical continuity or path for current flow through the component, as it is disconnected or broken.
An ohmmeter is a type of electrical metre that measures electrical resistance. When in resistance-measuring mode, multimeters also operate as ohmmeters. An ohmmeter measures the resistance of a circuit or component by passing electricity through it.
An ohmmeter is a device used to measure the electrical resistance of a circuit component or material. It works by sending a known current through the component and measuring the voltage drop across it. The ohmmeter then uses Ohm's Law (V=IR) to calculate the resistance of the component in ohms. This measurement helps in troubleshooting electrical circuits, testing the integrity of components, and determining if there are any faults or breaks in the circuit.
In a series circuit, a necessary condition is that all components are connected in a single loop, such that the same current passes through each component in sequence. If one component fails or is disconnected, the entire circuit will be interrupted.
Not at all. When the GPS is connected the circuit is closed/complete. Once the unit is disconnected the circuit is open and electricity doesnt make a full pass from negative to positive.
when the wire is disconnected from the dry cell you feel not hot
A circuit connected in a single path is called a series circuit. In a series circuit, the current flows through each component in sequence, providing only one path for the electricity to follow. If one component fails, the entire circuit is disrupted.
