The Ohm’s Law Apparatus (With Power Supply) is a comprehensive laboratory instrument designed for the demonstration and verification of Ohm’s Law, featuring a built-in regulated power source for convenient and precise experimentation.
Description
Integrated Power Supply: The apparatus comes complete with a built-in adjustable power supply, eliminating the need for external batteries or DC sources. This enables stable voltage variation across the test resistor or resistance wire.
Apparatus Construction:
Contains a mounted resistance wire (commonly nichrome or manganin) secured between terminals.
Includes precision meters—ammeter for measuring current and voltmeter for measuring voltage across the resistor.
Circuit arrangement is contained on a durable base, with clearly marked terminals for safe connections.
Features:
Smooth voltage adjustment through an integrated knob or dial.
Accurate voltage and current readings for each setting.
Ideal for repetitive classroom and laboratory demonstrations.
Operation: The user gradually increases the supplied voltage from the power supply, recording the corresponding current values. Plotting voltage versus current (V vs I) confirms Ohm’s Law, showing a linear relationship, with the slope indicating resistance.
This self-contained unit is essential for electrical experiments where precise control and ease of use are priorities, supporting education in physics and electronics by reliably verifying the principle

Description
The apparatus includes a mounted resistance wire (such as nichrome or manganin), connected securely between terminals, allowing for controlled voltage application and measurement of current.
A built-in regulated power supply is included, enabling smooth adjustment of voltage across the resistance element without needing external batteries or sources.
Standard instrumentation includes both an ammeter and a voltmeter for direct measurement of current through and voltage across the resistor.
All components are securely arranged on a durable base, with clear markings for easy connections and safe operation in a classroom or laboratory setting.
Operation
Voltage is gradually increased using the integrated power supply, while current readings are taken for each setting.
