Capacity Box Dial Type
Product Code : JA-PLE-4179
The Capacity Box Dial Type (SKU JA-PLE-4179) is a switched standard of capacitance for electrical measurements in the physics laboratory. High-grade paper condensers of accurate value are housed in a wrinkled-finish metal case and selected with rotary dials of ten steps each. This dial type capacity box is offered with one, two, three or four dials covering 0.001 to 1 microfarad, for college, B.Sc and senior-school electricity practicals.
Specifications
Each dial selects ten steps of one decade, so a single-dial box gives 10 steps, a two-dial box 20, a three-dial box 30 and a four-dial box 40 steps, with sub-divisions of 0.001, 0.01, 0.1 or 1 microfarad (mfd) per dial.

Uses of the dial type capacity box
The dial type capacity box is used wherever a known, adjustable capacitance is needed in a circuit: as the standard arm of a capacitance bridge, as the timing capacitor in charging and discharging experiments, and for comparing unknown capacitors.
- Standard capacitance in bridge methods such as the De Sauty bridge for comparing capacitances
- Charging and discharging of a capacitor through a resistor and study of RC time constant
- Series and parallel combination of capacitors
- Tuning and filter experiments in AC and electronics practicals
- B.Sc physics and engineering physics electricity and magnetism laboratories
