Hybrid Parameters Question & Answers March 21, 2022 By WatElectronics This article lists 50 Hybrid Parameters MCQs for Engineering Students. All the Hybrid Parameters Questions & Answers given below includes solution and link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up their fundamentals on the hybrid parameters. In electronics, the hybrid parameters are very useful in determining some of the amplifier characteristics. The hybrid parameters are represented by a letter h, and these parameters have mixed dimensions, because of mixed dimensions we call this parameter the hybrid parameter. The h parameters are easy to measure, convenient to use in circuit design and analysis, and they are easily convertible from one to another configuration. It is very useful in determining the input and output impedance as well as the voltage and current gain of the amplifier. The hybrid parameters are easy to measure and convenient to use in circuit analysis and design. The hybrid models were widely used before the popularity of re-model, re-model is also known as the dynamic emitter resistance model. In the case of the hybrid model, the parameters are defined in general terms for any operating conditions whereas in the case of the re-model the parameters are defined by the actual operating conditions. These hybrid parameters are very useful during the small-signal analysis of the transistor. The hybrid model is one of the equivalent models of transistors used in the small-signal analysis. The main advantage of the hybrid method is the circuit components are easily available and the procedure is easy to understand and quite simple. 1).
