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

Kirchhoff’s Law Kirchhoff’s current law (KCL) imposes constraints on the currents in the branches that are attached to each node of a circuit. In simplest terms‚ KCL states that the sum of the currents that are entering a given node must equal the sum of the currents that are leaving the node. Thus‚ the set of currents in branches attached to a given node can be partitioned into two groups whose orientation is away from (into) the node. The two groups must contain the same net current. In general

Acromioclavicular (AC) joint injury occurs on the top part of the shoulder where the collarbone attaches to the front side of the shoulder. The injury can be caused in different ways such as repetitive use of the shoulder or a fall. AC injuries are common to more men than women aged below 35 years. This is majorly because most of these individuals are much likely to participate in high-risk activities such as sports‚ or even work-related tasks like roofing. AC joint can be handled effectively by
