Question&answer and the h-parameters are given by: hie – The input impedance of the transistor (corresponding to the emitter resistance re). hre – Represents the dependence of the transistor’s IB–VBE curve on the value of VCE. It is usually very small and is often neglected (assumed to be zero). hfe – The current-gain of the transistor. This parameter is often specified as hFE or the DC current-gain (βDC) in datasheets. hoe – The output impedance of transistor. This term is usually specified as an admittance

Part 2: Safe work with large inductances 1. One of the main hazards of using inductances is electrical energy stored in the magnetic field. If a circuit containing an inductance is interrupted then the stored energy can release through air (forming an arc). This can destroy a switch contact‚ burn fingers‚ create other damage. In the circuit of Figure 1‚ show how to mitigate the risk (pay attention to polarity!). We give the elements in this circuit some simple values for the purpose of

CIRCUITS LABORATORY EXPERIMENT 3 AC Circuit Analysis 3.1 Introduction The steady-state behavior of circuits energized by sinusoidal sources is an important area of study for several reasons. First‚ the generation‚ transmission‚ distribution‚ and consumption of electric energy occur under essentially sinusoidal steady-state conditions. Second‚ an understanding of sinusoidal behavior makes possible the prediction of circuit behavior when nonsinusoidal sources are used through the use of techniques

incurred known as the matching principle. The cash basis accounting is a process company’s use only when cash is received. This process is also recorded also when cash is paid. This process is generally prohibited as an accepted accounting process due to its inability to record revenue when earned. This process also does not record expenses incurred. Create Adjusting Entries (Freddy) The importance of knowing how to adjust entries is to ensure that the revenue and matching principles are followed

Alternating current bridges….it’s applications and various perspectives revealed….. ALTERNATING CURRENT BRIDGES:- INTRODUCTION:- A bridge circuit is a type of electrical circuit in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging points is often adjustable when

In this lab‚ we were given an LED nightlight circuit. Upon first glance we noticed all the components‚ the zener diode‚ 3 resistors‚ a capacitor‚ 4 diodes‚ a photocell‚ an LED light‚ and something we thought was a transistor. We knew the first thing to do was to identify all of the components and find out the rating for them. We had to use the microscope to determine the identifying numbers on the zener diode‚ the capacitor‚ and the‚ assumed‚ transistor. The zener diode read 1N5242B‚ the capacitor
