13.

If an open capacitor is checked with an ohmmeter, the needle will:

 [A]. stay on zero [B]. stay on infinity [C]. move from zero to infinity [D]. move from infinity to zero

Explanation:

No answer description available for this question.

 Seshendra said: (Nov 17, 2010) We know that the capacitive reactance is 1/(2*pi*f*c)... Given that the capacitor is free from a source... So frequency applied for that capacitor is 0... So 1/(2*pi*0*c)=infinity...

 Shaan said: (Jun 24, 2012) But Capacitor at instant t=0 - works like a short ? Then As per transient analysis it should move from 0 to infinity.

 Gayu said: (Jan 16, 2014) At a given condition, if the capacitor was charged it makes infinity, else zero. It depends upon the charge.

 Urajanr said: (Apr 25, 2016) That's why the best is to use LCR where some level of frequency is pumped in to get the correct reading.

 Archana said: (Dec 13, 2017) Actually, we know capacitive reactance is 1/2*π*f*c. Here applied frequency is zero. So capacitive reactance is infinity.

 Shadan said: (Mar 15, 2018) Capacitor open means circuit open then resistance infinity so ohmmeter read infinute resistance.

 Zero said: (Mar 26, 2019) Infinity resistance because of dielectric metirial used in capacitor.

 Meow said: (Dec 9, 2019) It should be from zero to infinity (option C). At time=inf is only the time your Xc would equal to infinite.
