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 an equal deflection in both cases i.e., before and after reversing the probes if the chosen component is resistor.
Multimeter shows NO deflection in both cases i.e. before and after reversing the probes if the chosen component is capacitor
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 NO deflection in both cases i.e. before and after reversing the probes is the chsosen component is metal wire.
Solution
Multimeter shows NO deflection in both cases i.e. before and after reversing the probes if the chosen component is capacitor.
Multimeter shows deflection when it connects with capacitor
If we assume that LED has negligiable resistance then multimeter shows no deflection for the forward bias but when it connects in reverse direction, it break down occurs so splash of light out.
The resistance of metal wire may be taken zero, so no deflection in multimeter
No matter, how we connect the resistance across multimeter It shows same deflection.
