electrical insulation A material that resists electrical current flow. electrical load A consumer of electrical energy, turning it into light, heat, mechanical power, data, or chemical changes. electrical machine Motors and generators, apparatus that converts between electrical power and mechanical power. electrical measurements
Insulative materials prevent or limit the flow of electrons across their surface or through their volume. Insulative materials have a high electrical resistance and are difficult to ground, thus are not ESD materials. Static charges remain in place on these materials for a very long time.
Indirect materials cost: Indirect materials cost is the cost associated with consumables, such as lubricants, grease, and water, that are not used as raw materials. Other indirect manufacturing cost: includes machine depreciation, land rent , property insurance , electricity , freight and transportation, or any expenses that keep the factory ...
