Electrical Circuit Theorems for Circuit Analysis
Electrical Circuit Theorems: To solve problems in electrical networks, there are number circuit theorems have been developed like (1) Kirchhoff's laws (2) Superposition theorem (3) Thevenin theorem (4) Norton Theorem (5) The maximum power transfer theorem In this post we have listed all these theorems. We believe that this post will serve as a ready reference for you. Kirchhoff's laws: (a) Current Law: At any junction in an electric circuit the total current flowing towards that junction is equal to the total current flowing away from the junction, i.e. I =0 (b) Voltage Law: In any closed loop in a network, the algebraic sum of the voltage drops (i.e.products of current and resistance) taken around the loop is equal to the resultant e.m.f. acting in that loop. Superposition Theorem: In any network made up of linear resistances and containing more than one source of EMF, the resultant current flowing in any branch is the algebraic sum of the currents that would flow in that ...
