Which of the following will not be observed when a multimeter (operating in resistance measuring mode) probes connected across a component, are just reversed?
Multimeter shows no deflection in both cases i.e. before and after reversing the probes if the chosen component is metal wire.
Multimeter shows a deflection, accompanied by a splash of light out of connected component in one direction and no deflection on reversing the probes if the chosen component is LED.
Multimeter shows an equal deflection in both cases i.e. before and after reversing the probes if the chosen component is a resistor.
Multimeter shows no deflection in both cases i.e. before and after reversing the probes if the chosen component is a capacitor.

Solution
The correct option is D
Multimeter shows no deflection in both cases i.e. before and after reversing the probes if the chosen component is a capacitor.
Multimeter :
A volt-ohm-milliammeter (VOM) is a multimeter that can measure voltage, resistance, and current. It features voltmeter, ammeter, and ohmmeter operations. It is capable of measuring a wide range of electrical properties.
The explanation for the correct answer: The multimeter does not deflect before and after reversing the probes in the case of a capacitor.
The explanation for the incorrect answer :
-In the case of a resistor, the multimeter shows an equal deflection before and after reversing the probes in both cases.
- When inverting the probes on a metal wire, the multimeter does not show any deflection before and after.
- When the probes are reversed, the multimeter indicates deflection in one direction, accompanied by a splash of light from the connected component, but no deflection when the probes are reversed in the case of an LED.
