Now that we have the value of i1 and i2, we can find the voltage drops in each resistor.

How to Use Mesh Current AnalysisДЄ mesh is the single closed loop indicated in a circuit. The mesh analysis is only applicable to planner circuits or networks, which are simpler and no crossover wires present. It is a well-organized method for solving a circuit, but to analyze a network with mesh analysis, we need to fulfill certain conditions. It is especially useful if you have to solve it without a calculator.

Mesh analysis or mesh current analysis is used to solve a circuit with less unknown variables and less simultaneous equations. Since the KVL is also called the mesh rule, we can link it to mesh current analysis. Simply put, it says that the algebraic sum of all voltages in a loop must be equal to zero. KVL states that the directed sum of the potential differences (voltages) around any closed loop is zero. This is also called KirchhoffвЂ™s second law or KirchhoffвЂ™s loop (or mesh) rule. The second fundamental law in circuit analysis is the KirchhoffвЂ™s Voltage Law or KVL. Now that we have the value of V 1 and V 2, we can find the current flowing to each branch. Substitute the value to any of the two equations to get V 2. Now that we have the two equations for the two unknowns, we can start solving.ДЄpply cancellation for the two equations. To make it easier, let us assume that currents entering a node is positive while current leaving a node is 1 or V 1: i 1 вЂ“ i 3 вЂ“ i 2 = 2 or V 2: i 2 вЂ“ i 4 + 4 = 0Д®xpressing these two equations in terms of V 1 and V 2, we 2, And since we have two nodes, we need to write two equations. Express each current through V 1 and V 2 using OhmвЂ™s Law. We also need to assign currents flowing to each branch: To make it easier, we need to assign polarities to the resistors according to the current direction. To get the current equations for each element, we need to apply OhmвЂ™s Law, which states that the current is equal to the difference between the high and low potential, divided by resistance. To illustrate, let us look at the circuit below. The node voltage method of analysis solves for unknown voltages at circuit nodes in terms of a system of KCL equations. Nodal analysis or node-voltage analysis method determines the voltage (potential difference) between вЂnodesвЂ™ in an electrical circuit in terms of the branch currents. Since the KCL is also called as the nodal rule, we can then link it to nodal voltage analysis. Gustav Kirchhoff based his idea on the law of Conservation of Charge. In other words, KCL states that the algebraic sum of all currents entering and exiting a node must be equal to zero. It states that the t otal current entering a junction or node is equal to the current leaving the node, as no current is lost within the node. It is one of the fundamental laws used for circuit analysis. KirchhoffвЂ™s Current Law (KCL) is also known as KirchhoffвЂ™s first law, KirchhoffвЂ™s point rule, or KirchhoffвЂ™s junction rule (or nodal rule). These are basic network laws namely: (1) KCL or KirchhoffвЂ™s Current Law, and (2) KVL or KirchhoffвЂ™s Voltage Law. There are two essential laws we need to learn for circuit analysis. When doing circuit analysis, we need to understand the electrical quantities, relationships, theorems, and some essential laws. By this analysis, we can find the unknown elements of a circuit, such as voltage, current, resistance, impedance, power, among others, across its component. It is the process of studying and analyzing electrical quantities through calculations. Now, what is circuit analysis? It is the mathematical analysis of an electrical or electronic circuit. Building circuits is about taking advantage of electricity to build useful devices for our everyday life. An electronic circuit is a system composed of electronic components such as resistors, transistors, capacitors, inductors, diodes, and a lot more, connected by wires through which electric current can flow.
