Final answer:
The * symbol does not have a standard meaning in electrical diagrams, but other symbols represent components like motors and magnetic coils. The behavior of coils in a circuit involves converting electrical energy to mechanical work via magnetic forces when a switch is manipulated.
Step-by-step explanation:
In the context of an electrically operated switch, the * symbol typically does not have a standard meaning associated with it; the meaning can vary based on the schematic or the manufacturer of the electrical components. However, when considering electrical diagrams, common symbols used for electrical components include a circle or a pair of parallel lines for a motor, a coil symbol for a magnetic coil, and sometimes a symbol with a bimetallic strip or other design for a thermal element.
Regarding the behavior of coils in an electrical circuit, motors are a common application where magnetic force is applied on current-carrying wires. When current is passed through the loops in a magnetic field, it exerts a torque on the loops, which in turn rotates a shaft, converting electrical energy to mechanical work in the process. This principle is applied in various situations, such as when a switch is closed, allowing current to flow and potentially when a switch is opened, altering the current flow due to a change in magnetic flux.
