Which of the following will NOT be observed when a multimeter (operating in resistance measuring mode) probes connected across a component, are just reversed?
  • AMultimeter shows $NO$ deflection in both cases i.e. before and after reversing the probes if the chosen component is capacitor.
  • BMultimeter 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 $LED.$
  • CMultimeter 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.

    A student uses the resistance of a known resistor $(1 \,\Omega)$ to calibrate a voltmeter and an ammeter using the circuits shown below. The student measures the ratio of the voltage to current to be $1 \times 10^3 \,\Omega$ in circuit $(a)$ and $0.999 \,\Omega$ in circuit $(b)$. From these measurements, the resistance (in $\Omega$ ) of the voltmeter and ammeter are found to be close to
