Ohms Law Apparatus (with Power Supply)
Product Code : SCL-PLE-11849
The StemAids Ohm’s Law Apparatus is an all-in-one laboratory workstation engineered for the empirical verification of the relationship between current, voltage, and resistance. Unlike basic setups that require external batteries, this unit features a Built-in Regulated DC Power Supply, providing a stable and safe potential difference for student experimentation. Manufactured to ISO 9001:2015 standards, it is a foundational platform for University and Technical College physics labs to quantify the electrical characteristics of Ohmic conductors.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Circuit Interface: Facilitates student understanding of how potential difference drives charge flow through a conductor, supporting the core curriculum of Electromagnetism.
- V-I Relationship Quantification: Enables the physical plotting of the V=IR relationship; learners apply incremental voltage changes and record the resulting current to observe proportionality.
- Resistance Evaluation: Supports the analysis of "Slope" in a V-I graph; students evaluate experimental data to calculate the resistance value (R=V/I) and compare it with the theoretical value.
- Measurement Accuracy Evaluation: Allows students to evaluate the impact of internal resistance and human error in analog vs. digital readings, fostering higher standards for laboratory data integrity.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant). The unit is housed in high-density polyethylene (PE) foam to protect the internal transformer and the delicate movements of the monitoring meters during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a detailed laboratory manual with standardized experimental procedures.
- Durability: Tropicalized design featuring moisture-resistant PCBs and vacuum-impregnated transformers, ensuring reliable operation in high-humidity or non-climate-controlled environments.
Direct OEM Sourcing Advantages
Procuring the StemAids Ohm’s Law Apparatus directly ensures vertical manufacturing control:
- Regulated DC Precision: We utilize high-stability internal IC regulation to ensure the variable DC source is free from "jitter," which is essential for plotting perfectly linear V-I curves.
- Precision Load Selection: Direct oversight of the internal load resistors ensures they have a low temperature coefficient, preventing the resistance from drifting as the components warm up during experiments.
- Direct Factory Spares Availability: Guaranteed availability of replacement potentiometers, meters, and safety terminals to maximize the long-term ROI of institutional science kits.
- Manufacturing Control: Direct oversight of the grounding (earthing) and double-insulation protocols ensures the highest level of operator safety for students.
