Detailed Solution

Hybridization of carbon in diamond is $S p^{3} .$ In diamond four valency electrons are participate in bonding so it is bad conductor of electricity. In graphite carbon hybridization is $S p^{2} .$ Out of four electron, three electrons are participated in bonding.The fourth free electron is participating in delocalisation and increase the conductivity.
