Key Features
- Low-voltage, high-current output, 1-0-1 V nominal a.c.
- Choice of 1 V a.c. or 2 V d.c.
- D.c. output produced by rectifying 2 V a.c. (unsmoothed).
- 40 A Schottky barrier diode for robust, efficient rectification.
- Tolerates short circuit; the transformer is protected by thermal fuses and a slow-blow fuse.
Technical Specifications
| Specification | Value |
|---|---|
| A.c. output | 1-0-1 V nominal (1 V a.c.) |
| D.c. output | 2 V d.c., rectified, unsmoothed |
| Short-circuit current | 10 A |
| Rectifier | 40 A Schottky barrier diode |
| Protection | Thermal fuses and slow-blow fuse |
How It Is Used
The unit supplies the heavy currents needed in electromagnetism practicals, such as force-on-a-conductor work with Fleming's apparatus, at a safe low voltage. Because it tolerates short circuits, low-resistance set-ups can be connected without damaging the supply.
Frequently Asked Questions
What outputs does the Electromagnetic Power Supply give?
It gives 1 V a.c. or 2 V d.c. The d.c. output comes from rectifying 2 V a.c. and is unsmoothed.
Is the Electromagnetic Power Supply protected against short circuits?
Yes. It tolerates short circuit, with a short-circuit current of 10 A, and its transformer is protected by thermal fuses and a slow-blow fuse.
