Abstract: To simplify a complex electrical circuit, there are various network reduction techniques. These techniques include star delta conversion, series parallel conversion, source transformation, Kirchoff law.  Network theorem etc. The network theorems not only reduce or simplify the networks but also helps in calculating the network parameters.

Reciprocity theorem and RC series network are both part of syllabus engineering of course, network analysis of semester 4 of electrical program. Both these kits are developed, tested and are ready to use for laboratory purpose. These kits are developed at Rajeev Electricals. The industry expert Mr. Damle guided us in preparing the two kits. This experiential learning helped us getting the technical experience and also gave us industry exposure which definitely helped us understand the expectation of industry from a budding engineer.

The reciprocity theorem [1] is a fundamental principle in electrical engineering and physics that establishes a relationship between the electrical behaviour of two circuits. (Source and load). It states that the effect of a current in one circuit on the electric field in another circuit is the same as the effect of the same current in the second circuit on the electric field in the first circuit.

The RC series circuit is a fundamental electrical circuit consisting of a resistor and a capacitor connected in series across a voltage source. When a voltage is applied, the capacitor charges up gradually. The time it takes for the capacitor to charge is determined by time constant, which is RC that is the product of the resistance and capacitance in the circuit. When the voltage source is removed, the capacitor begins to discharge through the resistor.
