Physics Diagrams

Physics diagrams are very helpful to understand the basic concept of physics. If we learn physics diagrams carefully we can visualize any topics and remember the concept for a very long time. In physics generally, we use a free body diagram or FBD to understand the concept. FBD diagrams are mainly the graphical presentation of the concept which helps to visualize such as applied force, movement of the body.

Circuit Diagram

The circuit diagram is a path through which an electric current passes. It is the graphical presentation of an electrical circuit. A circuit diagram represents the original connections of a circuit. There are also circuit breakers that protect other devices connected to the circuit.

Schematic Diagram

A schematic diagram mainly represents the elements of a system and it uses graphic symbols to represent the system. These diagrams are drawn to avoid irrelevant information given in the problems.

Energy Band Diagram

The energy band is mainly the range of energies that an electron can possess in an atom. The energy band diagram mainly plots various key energy levels as a function of spatial dimensions. There is a difference between ban structure and energy band so we should not be confused between them. There are mainly three energy bands such as valence band, conduction band, forbidden band.

Ray Diagram

Ray diagram mainly traces the line that light takes for a person to view a point on the image of an object. The lines are drawn on ray diagrams for incident rays and reflected rays. The main purposes of drawing ray diagrams are to trace and calculate the path of rays or waves, absorption characteristics.

Phasor Diagram

The phasor diagram represents mainly a sinusoidal function in which angular frequency, amplitude, and initial phase are actually time-invariant. It is a complex number. Phasor is mainly a vector that represents the value of the vector quantity at the one end and on the other end, it represents the end of the vector that rotates. Lead and lag mainly represent the relationship of a waveform to the other with a sinusoidal expression.

Example AC Generator

Ac generator mainly converts mechanical energy into a different form of alternating electrical energy. We use a circuit diagram to understand the AC generator principle. The principle in which the AC generator works is the principle of electromagnetic induction. In an AC generator, a coil rotates in a uniform magnetic field in which the axis of the coil is perpendicular to the axis of the magnetic field. So when the magnetic field lines pass through the coil an emf is produced which causes current flow in the circuit.

FAQs about Physics Diagram

Q.1 What are diagrams?

Answer: Vector diagrams mainly represent the direction and the magnitude of a vector. Vector diagrams can describe the velocity of a moving object when the object is in motion.

Q.2: Are force and temperature scalar quantity?

Answer:  Temperature is actually a scalar quantity as the temperature does not have any direction. But on the other hand, force is a vector quantity as it has both magnitude and direction.
