In electrical engineering, "resistances" refer to the opposition that a material offers to the flow of electric current. Measured in ohms, resistance determines how much current will flow through a circuit when a voltage is applied. Materials like copper have low resistance, making them good conductors, while rubber has high resistance, acting as an insulator. In a broader context, "resistances" can also refer to the forces or factors that oppose change or progress in various fields, such as social movements or organizational behavior. For example, social resistance can occur when individuals or groups oppose new policies or reforms, often due to fear of the unknown or attachment to the status quo.
