Which of the following will NOT be observed when a multimeter (operating in resistance measuring mode) probes connected across a component, are just reversed?
- A Multimeter shows \(NO\) deflection in both cases i.e. before and after reversing the probes if the chosen component is capacitor.
- B 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 \(LED.\)
- C Multimeter shows \(NO\) deflection in both cases i.e. before and after reversing the probes if the chosen compoenent is metal wire.
- D Multimeter shows an equal deflection in both cases i.e. before and after reversing the probes if the chosen component is resistor.
Answer & Solution
Correct Answer
(A) Multimeter shows \(NO\) deflection in both cases i.e. before and after reversing the probes if the chosen component is capacitor.
Step-by-step Solution
Detailed explanation
\((1)\) Multimeter shows deflection when it connects with capacitor \((2)\) If we assume that \(LED\) has negligiable resistance then multimeter shows no deflection for the forward blas but when it connects in reverse direction, it break down occurs so splash of light out.…
