Description
The Ohm’s Law Apparatus is a precision educational instrument designed to experimentally verify Ohm’s Law, which states that the current through a conductor is directly proportional to the applied voltage, provided physical conditions remain constant. This apparatus allows students to study the V–I relationship, calculate resistance, and plot characteristic curves with high accuracy.
Ideal for physics laboratories, electronics labs, engineering colleges, polytechnic institutes, and technical training centers.
