Product Information
Physics Laboratory Equipment & Training KitOhm's Law Apparatus with Built-in Power Supply
An advanced, comprehensive, and all-in-one experimental setup designed for accurate verification of Ohm's Law, calculating resistance, and analyzing V-I characteristics in physics and electrical engineering laboratories.
Product Overview & Importance
Our Ohm's Law Apparatus with Built-in Power Supply is engineered to provide students, educators, and laboratory technicians with a streamlined, clutter-free testing environment. Traditional experimental setups require separate DC power adapters, multimeters, and loose resistor panels, which often lead to wiring errors and messy lab benches. This self-contained unit integrates everything onto a single, robust panel.
Designed to demonstrate the fundamental relationship between Voltage (V), Current (I), and Resistance (R) as defined by Ohm's Law (V = I × R), this apparatus guarantees high stability, crystal-clear meter readings, and long-term durability for high schools, polytechnic institutes, and university engineering departments.
Theoretical Background & Principle
Ohm's Law states that the current passing through a conductor between two points is directly proportional to the voltage across the two points, provided physical conditions (such as temperature) remain constant. Mathematically expressed as V = I × R.
Using this training kit, students can dynamically adjust the built-in variable rheostat, record corresponding values on the precision voltmeter and milliammeter, and plot a linear V-I graph to verify the law with exceptional laboratory accuracy.
Key Features & Advantages
All-in-One Integrated Design
Features an inbuilt regulated DC power supply, voltmeter, ammeter, and variable rheostat, eliminating extra components.
High Precision Calibration
Equipped with high-grade moving-coil / digital meters ensuring accurate, stable, and repeatable data for calculations.
Student Safety Compliant
Housed in a shock-proof, insulated heavy-duty body equipped with secure, insulated 4mm safety terminal sockets.
Built for Heavy Lab Usage
Robust manufacturing standards designed specifically to endure daily, rigorous handling across student practical sessions.
Step-by-Step Experimental Procedure
Conducting experiments with this kit is straightforward and structured for maximum educational efficiency:
- Circuit Connection: Ensure all patch cords are securely plugged into the respective 4mm insulated terminals as per the printed circuit diagram.
- Power Activation: Turn on the unit utilizing the main power switch to activate the built-in regulated DC power supply.
- Varying Resistance: Slowly adjust the knob of the built-in wire-wound rheostat to alter the circuit resistance incrementally.
- Recording Readings: Note down the simultaneous readings displayed on the Voltmeter (V) and Ammeter (I) for each step.
- Verification & Graphing: Calculate the ratio of V to I to find resistance (R) and plot a graph to visually verify Ohm's law.
