About This Product
A capacitance substitution box lets students put an adjustable capacitance into a circuit without changing components. In electronics practicals it is used to try different capacitor values, for example when studying how charging and discharging time changes with capacitance, or when matching a value needed in a circuit. Make before break switching keeps the circuit closed while the dial is turned from one step to the next.
