Decade Resistance Box

The Lascells Decade Resistance box provides a precise way to vary resistance in a circuit. With four decade dials, resistance can easily be tuned in the range from 1 to 9999 Ohms in 1 Ohm steps. The 4 mm sockets allow for easy connection to student circuits, and allow for the unit to be used as a potential divider.

Perfect for any electronics experiment that requires variable resistance, or a range of resistance values, including:

• Verifying Ohm’s Law
• Effect of resistance on the time constant in RC circuits
• Potential divider investigations
• Fine-tuning cutoff frequencies in the design of op-amp-based filter circuits

Resistors are 1% tolerance. Max current 0.35 A. Power rating 1 W continuous.
