Ohm's Law Apparatus (with Power Supply)
Product Code : SCL-PLE-11849
Quick Answer: The Ohm’s Law Apparatus (with Power Supply) has its own regulated 0–12 V variable DC supply, fixed resistors, a 0–15 V voltmeter and an ammeter on one panel, so Ohm's law experiments can be run without batteries.

Key Features
- Built-in regulated, continuously variable DC supply of 0–12 V.
- Two meters give voltage and current readings at the same time.
- Voltmeter range of 0–15 V DC.
- Fixed standard resistors on the board.
- Current-limiting protection and an internal glass fuse.
Technical Specifications
| Specification | Value |
|---|---|
| DC supply | Built-in, regulated, 0–12 V, continuously variable |
| Voltmeter range | 0–15 V DC |
| Load | On-board fixed standard resistors |
| Connections | 4 mm safety-shrouded sockets, printed circuit mimic |
| Protection | Current limiting, internal glass fuse |
| Enclosure | Metal, anti-corrosive powder coating |
How It Is Used
Students wire the resistor, ammeter and voltmeter following the printed mimic, then raise the built-in supply in steps and note each pair of readings. A straight-line graph of voltage against current confirms that the current through an ohmic conductor is proportional to the voltage across it.
