230v L-N, and 70v L-E

Looking at my lighting earlier and see that my multimeter is measuring 230v from live to neutral at the ceiling light, but only70 ish volts from live to earth. Am I right in thinking the earth may be disconnected somewhere and the 70ish volts im reading is due to capacitance ? I cannot get my head round why its like this   The live is definately at 230v so if the earth was disconnected I should not be getting any reading atall. Where is this 70v reading from ???? and between what ?? I need to check the continuity of the earth tomorrow but it cannot be continuous or i would be getting 230v, even a loose earth connection would still read full voltage would it not ??
  • But current flowing in capacitance is out of phase with the driving voltage, so does not represent any dissipation

    Unless the current (charge) can 'escape' via the load? (the energy to make CFLs flicker has to come from somewhere).
