Explore the fundamentals of circuit theory, including nodes, branches, loops, and the interconnection of components; distinguish independent and dependent sources; define emf and current, and lay groundwork for dc analysis.
Explore Ohm's law and how voltage, current, and resistance determine circuit behavior, including how conductors and resistors shape current flow in parallel paths.
Use Ohm's law to find current in a 6-volt circuit, with I = V/R (6/4 = 1.5 A, 6/6 = 1 A), showing that resistance lowers current, including parallel cases.
Apply Kirchhoff's laws to analyze circuits by balancing currents at nodes (KCL) and summing voltages around loops (KVL) to derive currents and voltages.
Explore the voltage division rule and current division to analyze voltage drops and currents in series and parallel circuits using Ohm's law.
Learn how to apply the current division rule to find currents in parallel resistors and analyze parallel and series relationships, using the equivalent resistance concept.
Learn how to find equivalent resistance in mixed series and parallel networks by reducing circuits step by step, using parallel and series formulas and current division.
Apply Ohm's law and current division to solve problems with series and parallel resistor networks, determine equivalent resistance and branch currents.
This lecture reviews series and parallel circuits, explaining how current splits across branches and how resistance values affect total current from a battery.
Identify the reference node and all circuit nodes, then apply nodal analysis to write and solve Kirchhoff's current law equations for node voltages, such as v_x, in multi-branch networks.
Explore source transformation, converting between voltage and current sources with series or parallel resistances to simplify circuit analysis and solve currents and voltages more easily.
Explore star to delta conversion (Y to delta) to simplify circuit analysis, compute equal resistances, and apply parallel combinations.
Circuit Analysis is a part of electric and electronics. Circuit Analysis is used to find current and voltages in any part of the circuits. this course contains complete DC analysis methods to find required voltage and current in the circuits. it is done by various laws and theorems to facilitate the analysis part. As a part of this course some of the gate questions also solved here an there. There are quiz sections available in this course. Learners can take up the quiz to test the level of understanding.
This course is mainly intended to provide a sound foundation to engineering students who are begin to learn circuit analysis. i strongly recommend this course to all first year engineering students and specifically would be helpful for electronics and communication students, Electrical engineering department students, Instrumentation engineering department students.
