Resistance Coil Unit
Product Code : SCL-PLE-11790
Quick Answer: The Resistance Coil Unit houses several non-inductively wound resistance coils in one case, so students can change values quickly when checking series and parallel combinations and Kirchhoff’s laws. Coil tolerance is ±1% to ±2%.

Key Features
- Several precision-wound coils in a single chassis.
- Non-inductive winding on every coil.
- Tolerance of ±1% to ±2% across the internal coils.
- Rated 1–5 W per coil for standard lab DC supplies.
Technical Specifications
| Specification | Value |
|---|---|
| Elements | Multiple non-inductively wound coils |
| Tolerance | ±1% to ±2% |
| Power rating | 1–5 W per coil |
| Supply | Standard laboratory DC power supplies |
How It Is Used
Selected coils are connected in series, in parallel or in small networks with an ammeter and voltmeter. Measured currents and voltages are compared with values calculated from the coil ratings, to confirm the rules for combining resistances and Kirchhoff’s current and voltage laws.
Frequently Asked Questions
How does the Resistance Coil Unit differ from a single resistance coil?
It holds multiple coils in one chassis, so students can switch between resistance values quickly rather than handling separate coils.
