Resistance Box Electronic Type
Product Code : EL-EAE-10286
Quick answer: The Resistance Box Electronic Type is an economical toggle-switch resistance box for school physics laboratories. Each switch inserts or removes one resistance, and with every switch off the box reads zero. It is made in 50, 100, 500 and 1000 ohm versions. Lab Exports manufactures it in Delhi for schools and teaching laboratories.

How it is used
The box replaces the plugs of a traditional resistance box with toggle switches. Each switch is wired across one resistance: in the insert position the resistance is included in the circuit, and in the other position it is bypassed. The resistance between the terminals is the sum of the inserted values, and with every switch excluded it is zero.
Toggle switches are quick for students to operate and there are no loose plugs to misplace, which makes the box practical for large classes. It suits school experiments such as verifying Ohm's law, studying series and parallel combinations and controlling the current in simple circuits.
- Set all switches to the excluded position so the box reads zero.
- Connect the box into the circuit through its terminals.
- Switch in the resistances whose values add up to the value required.
- Record the setting with each meter reading and return all switches to zero after use.
