The term that describes the ability of a conductor's insulation to transmit an electric field is known as permittivity. This property quantifies how easily an electric field can penetrate a material and is a crucial factor in determining the capacitance of capacitors and the behavior of insulating materials in electrical applications. Permittivity is fundamentally related to the material's ability to store electrical energy within an electric field, which is important for designing various electronic and communication components. High permittivity materials are better at insulating against electric fields, making them essential in applications where preventing leakage or maintaining signal integrity is crucial. The other terms, while related to electrical properties, don't specifically describe the transmission of electric fields through insulation. Conductivity refers to a material's ability to conduct electricity, transmitability is not a standard term in this context, and capacitance pertains to the ability of a system to store an electric charge, which is influenced by permittivity but is not directly synonymous with it. This distinction helps clarify why permittivity is the correct choice in understanding how insulation interacts with electric fields.
