Product Code : SCL-EELE-14529
Indian Lab Suppliers supplies the Digital Ohm's Law Apparatus (Product ID: 14529) as part of its electronics engineering lab equipment range. It is a pre-wired Ohm's law set-up with a regulated DC supply, a variable resistor and a digital voltmeter and ammeter.
Quick Answer
A built-in regulated supply gives 0–12 V DC from AC mains (230 V or 110 V as required), and a variable resistor or rheostat changes the circuit resistance. Digital meters show voltage and current, typically up to 500 mA, so students can tabulate V against I and confirm that V/I stays constant for a fixed resistor (V = IR). The circuit is pre-assembled, with banana terminals or fixed test points, overload and short-circuit protection and an insulated housing. Please confirm the current range and mains voltage at quotation.
