Product Code : SCL-EE-12445
Quick Answer: The Digital Ohms Law Apparatus is a laboratory trainer for verifying Ohm’s law, letting students record voltage and current readings digitally and plot a V-I graph for a resistive circuit.
Last updated: October 2026
Key Features
- Verifies that current is proportional to voltage when resistance stays constant
- Digital voltage and current display section
- Supports plotting V-I graphs and identifying linear behaviour
- Trains students in digital meter reading and data recording
- Intended for supervised low-voltage experiments
About This Product
Students wire the circuit to the approved diagram, start the voltage at its lowest safe value and raise it gradually, recording the current at each step. Plotting voltage against current and checking whether the graph is linear confirms Ohm’s law, and the supply is switched off before any change of resistance or leads. It suits school and college physics and electronics practicals. The Digital Ohms Law Apparatus is available for supply within India and for export to Uruguay, Zambia, Oman, Cabo Verde, Ghana and Fiji.
Frequently Asked Questions
Q1. What result shows that Ohm’s law holds?
A linear graph of voltage against current at constant resistance shows that current is proportional to voltage, which is what Ohm’s law states.
