How does an electric generator differ from an electric motor in terms of their functions and operations?
An electric generator converts mechanical energy into electrical energy, while an electric motor converts electrical energy into mechanical energy. Generators produce electricity by rotating a coil within a magnetic field, while motors use electricity to create a magnetic field that causes a coil to rotate.

What is the difference between an electric generator and an electric motor, and how do their functions and mechanisms differ from each other?
An electric generator converts mechanical energy into electrical energy, while an electric motor converts electrical energy into mechanical energy. Generators use electromagnetic induction to produce electricity, while motors use the interaction between magnetic fields and electric currents to create motion. In summary, generators create electricity, while motors use electricity to create movement.
How does a generator produce static electricity?
A generator moves a coil of wire near a magnet, causing the electrons in the wire to move, creating an electric current. This movement of electrons is what generates static electricity in the form of a build-up of electric charge on the surface of the object.
How do photoreceptor cells, such as cones and rods, differ in their functions within the human eye?
Photoreceptor cells in the human eye, such as cones and rods, differ in their functions. Cones are responsible for color vision and detecting fine details, while rods are more sensitive to low light levels and help with night vision.
What is the difference between an electric field and a magnetic field, and how do their properties and interactions differ in various physical phenomena?
An electric field is a force field created by electric charges, while a magnetic field is a force field created by moving electric charges. Electric fields exert forces on charged particles, while magnetic fields exert forces on moving charged particles. In various physical phenomena, electric fields are responsible for phenomena like electric currents and static electricity, while magnetic fields are responsible for phenomena like magnetism and electromagnetic induction. Their interactions differ based on the nature of the charges and their movements involved.
What are state functions in thermodynamics and how do they differ from path functions?
State functions in thermodynamics are properties that depend only on the current state of a system, such as temperature, pressure, and internal energy. They do not depend on the path taken to reach that state. Path functions, on the other hand, depend on the specific path taken to reach a particular state, such as work and heat.
