Answer:
It depends on the state.
Step-by-step explanation:
Phosphorus sesquisulfide (p4s3) is a poor conductor of electricity because it is an ionic compound which is present in solid form. Ionic compounds in solid form are poor conductors of electricity due to tightly holding of their ions to one another while on the other hand, it is a good conductor of electricity in molten or liquid form due to its movement of ions in the liquid so it depends on the state of the compound.
