The IEC A.C.Theory Kit contains all the components necessary to perform a range of experiments for the teaching of A.C. electrical theory. The kit contains an accurate digital signal source to permit the student to study the effects of frequency on impedance and resonance. This 10 volt peak to peak signal source can provide all the current required for the experiments and is effectively the complete power source. Inductors are mounted in strong plastic bases and capacitors, resistors and switch are mounted in strong transparent plastic housings so that each is easily visible to help students recognise devices. The kit comes complete with a set of connecting cables with good quality 4mm banana plugs moulded to the cables. Two centre-zero meters are provided for ‘dynamic’ study of current and voltages. The digital multi-meter provided is for both AC and DC volts and amps and includes capacitance measurement.
