Using kirchhoff’s laws, it is possible to take a circuit with two loops and several power sources (figure 37) and determine loop equations, solve loop currents, and solve individual element. This approach requires two simultaneous equations formed by applying the voltage law to both loops Loop analysis is a systematic procedure based on kvl to solve for currents in more complex circuits
DC Circuit Examples
Loop current analysis involves the following steps
Identify loops in a circuit
Calculate the effect of placing real batteries in series and parallel by using kirchhoff's rules In this article we describe the special cases and show how to deal with them using the loop method The loop current method, just like the mesh current method, is based on kirchhoff's voltage law (kvl). As well as using mesh current analysis, we can also use node analysis to calculate the voltages around the loops, again reducing the amount of mathematics required using just kirchoff’s laws.
Examining a circuit with the node or loop methods can reduce the amount of time required to get important information on a circuit Another way of simplifying the complete set of kirchhoff’s equations is the mesh or loop current method Using this method, kirchhoff’s current law is satisfied automatically, and the loop equations. One most popular technique will be discussed in this lesson is known as ‘mesh or loop’ analysis method that based on the fundamental principles of circuits laws, namely, ohm’s law and kirchhoff’s voltage.
