Objective The aim of the experiment is to understand the properties of the passive elements and the resonance. Apparatus 1. Unknown Box 2. Passive Elements: Resistors, Inductors and Capacitors 3. A.C. Power supply 4. Connecting Wires 5. Multimeter Introductory Theory Passive elements Passive elements are elements that can either absorb energy or store energy. There are 3 types of passive elements, which are shown below: Resistor: A resistor is a two-terminal electrical or electronic component that resists an electric current …showed first 75 words of 1758 total…

Conclusion: In conclusion, there will be minimum current and maximum impedance when it reaches the resonant frequency, f o. The resonant frequency is 15.5 kHz.
