About This Product
A capacity box gives a set of known capacitances that can be selected by dial. In school and college physics it is used in bridge circuits to find an unknown capacitance by comparing it with known values, and to study how capacitors behave in a circuit. In the De-Sauty bridge, two capacitors are compared through the ratio of resistances in the arms, with a galvanometer used to find the balance point. Alongside supply within India, the Capacity Box Dial Type is offered for export to Egypt, Argentina, Latvia, Gambia, Kiribati and Vietnam.
Frequently Asked Questions
Q1. Which dial versions of the Capacity Box are listed?
Single dial with ten steps, two dial with 20 steps, three dial with 30 steps and four dial with 40 steps.
Q2. What does the De-Sauty bridge version include?
Three decade dials of x10, x100 and x1000 ohms form one arm, and the other arm has the same dials. A special Morse key is fitted at the centre of the arms for connecting the battery and galvanometer.
