Resistance Box 100 Ohms
Product Code : SCL-EAE-11278
Quick answer: The Resistance Box 100 Ohms gives selectable resistance of up to 100 ohms through its external terminals. Its low range suits practicals where small resistances matter, such as Ohm's law, voltage-drop comparisons and finding the internal resistance of a cell with a potentiometer. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
Changing a loose resistor for every reading is slow and risks poor connections. A resistance box keeps a range of values in one unit: the student selects a combination and the box presents that total between its terminals. With a total of only 100 ohms every setting is a low resistance, so the effect of each change on the current, and on the voltage across other parts of the circuit, is easy to follow.
- Place the box on a clean, dry, stable bench and check the marked values.
- Keep the supply off while making connections through the external terminals.
- Select the resistance combination required.
- Switch on, record the meter readings and repeat for other settings.
- For the internal-resistance experiment, connect the box across the cell on the potentiometer and select a low value before finding the balance length.

Frequently asked questions
When is a 100 ohm resistance box used instead of a larger one?
When the experiment needs low resistances, such as shunting a cell to find its internal resistance or studying voltage drops in low-resistance circuits.
What is included with the 100 ohm resistance box?
The listed supply is the resistance box itself. Leads, meters, switches and a power supply can be added to the same enquiry.
