A paper-filled capacitor is charged to a potential difference of
V_(0)=2.4V. The dielectric constant of paper is
\kappa =3.7. The capacitor is then disconnected from the charging circuit and the paper filling is withdrawn, allowing air to fill the gap terween the plates. Find the new potential difference
V_(1)of the capacitor. While the capacitor is disconnected from the charging circuit, an unknown substance is inserted between the plates. The plates then attain a potential difference that is 0.67 times the original potential difference
V_(0)(when paper filled the capacitor). What is this unknown substance's dielectric constant
\kappa _(u)?
K_(u)=IncorrectWhile the capacitor is disconnected from the charging circuit, an unknown substance is inserted between the plates. The plates then attain a potential difference that is 0.67 times the original potential difference
