Final answer:
A high conductance indicates that a material is a good conductor of electricity, which is the opposite of being unable to conduct current well, thus the statement is false.
Step-by-step explanation:
The statement that a high conductance of a material indicates that the material is not able to conduct current well is false. Conductance is a measure of how easily a material allows the flow of electric charge. Materials with high conductance, such as metals and salty water, are known as conductors because they have free electrons or ions that can move relatively freely, enabling them to conduct electric current effectively. Conversely, materials with low conductance are called insulators, and they do not allow electric charge to move through them easily. Examples of insulators include glass and pure water.
