Resistance Box 1000 Ohms
Product Code : SCL-EAE-11277
Quick answer: The Resistance Box 1000 Ohms provides known resistance values of up to 1000 ohms, chosen with top-mounted selectors and taken from its terminals. Students use it to verify Ohm's law, to see how resistance controls current, and as the known arm in bridge and comparison experiments. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How it is used
Inside the box the resistance is divided into sections, and the selectors add these sections together so that the value between the terminals is the sum of those chosen. In an Ohm's law practical, students keep the voltage fixed, change the selected resistance and watch the current fall as the resistance rises, I = V/R.
- Place the box on a stable, dry bench.
- Keep the power off while connecting the box into the circuit through its terminals.
- Select the required resistance from the marked values.
- Have the instructor check the circuit and the setting.
- Switch on and record the voltage or current, then change the setting for the next reading.
It also serves as the known resistance in metre bridge and Wheatstone bridge circuits, and for building series combinations with other resistors.
