Which of the following will NOT be observed when a multimeter (operating in resistance measuring mode ) probes connected across a component, are just reversed ?
Option: 1 Multimeter shows an equal deflection in both case i,e. before and after reversing the probes if the chosen component is resistor.
Option: 2 Multimeter shows NO deflection in both case i,e. before and after reversing the probes if the chosen component is capacitor.
Option: 3 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.
Option: 4 Multimeter shows NO deflection in both case i,e. before and after reversing the probes if the chosen component is metal wire.

1.No matter, how we connect the resistance across multimeter It shows the same deflection. 

2.Multimeter shows deflection when it connects with a capacitor.

So option 2 is the answer.

3.If we assume that LED has negligible resistance then the multimeter shows no deflection for the forward bias but when it connects in the reverse direction, it break down occurs so splash of light out.  

4.The resistance of the metal wire may be taken zero, so no deflection in the multimeter.
