Capacitor Box test tube and experiments that require specificThe Capacitor Box allows for the introduction of an adjustable capacitance value into any electrical circuit. The box operates on a 'Make before Break' switching arrangement, ensuring that the circuit is never open while making a selection. It features two terminals for connecting wires or 4mm banana plugs, as well as a third terminal for earthing or shielding the housing. Each dial has 10 steps Accuracy: typically + 5% Capacitors for 11 Steps: 100pF,
