Superposition Theorem
In a linear network consisting of resistances and voltage sources, the value of the current in any branch is the algebraic sum of the currents due to each e.m.f., when all the other sources are replaced by their internal resistances.

Maximum Power Transfer Theorem
The maximum power transfer theorem states that maximum power is transferred from source to the load when the internal resistance of the source is equal to the load resistance i.e. the power will be maximum when r = RL

It states that when a number of voltage sources V1, V2, V3… are connected in parallel having their internal resistances as (r1, r2, r3 …) respectively, then this arrangement can be replaced by a single equivalent voltage source (V) in series with an equivalent series resistance (r).

Simple Calculation Methods to Solve Problems of Mesh Analysis
In mesh analysis any resistive, inductive or capacitive circuit can be analysed to obtain current in any branch of the circuit. We shall use one simple example to understand mesh analysis.
