Dynamo Model AC DC Manufacturer,Supplier and Exporter in India
Product Code : SCL-ES-11433
Description:
The Educational Instruments Dynamo Model AC/DC is an innovative piece of Physics Science educational laboratory equipment designed to provide a hands-on, interactive understanding of electricity generation and the fundamental principles of electromagnetic induction. This model effectively illustrates how mechanical energy is converted into electrical energy, generating both Alternating Current (AC) and Direct Current (DC).
The standout feature is the inclusion of dedicated, separate armatures for AC and DC generation. This allows students to directly compare the construction and function of the AC generator (featuring slip rings) and the DC generator (featuring a commutator or split-ring). This experiential learning approach simplifies the complex notions of electricity, bridging the gap between theory and the real-world technology that powers homes and devices.
Usage:
The Dynamo Model is crucial for demonstrating the core concepts of Faraday's Law of Induction and the engineering distinction between AC and DC generators.
Electromagnetic Induction: The primary use is to manually rotate the armature within a magnetic field, allowing students to observe the direct generation of an electromotive force (EMF) and electric current. This directly verifies that relative motion between a conductor and a magnetic field induces voltage.
AC Generation Principle: Using the slip-ring armature, students can observe how the current generated continuously reverses direction, characteristic of Alternating Current. They can monitor this output using an external measuring device (like a galvanometer or oscilloscope).
DC Generation Principle: By switching to the commutator (split-ring) armature, students observe how the mechanical switching action rectifies the output, producing a pulsating but unidirectional Direct Current. This showcases the function of the commutator in electrical machinery.
Hands-on Energy Conversion: The model demonstrates the transformation of mechanical energy (the effort of turning the handle) into electrical energy, fostering a deeper appreciation for the physics behind electric power plants and renewable energy technologies.
