Tellegen’s theorem is based on the principle of law of __________.

Tellegen’s Theorem:

• According to Tellegen’s theorem, the summation of instantaneous powers for the n number of branches in an electrical network is zero.
• Let n number of branches in an electrical network have I₁, I₂, I₃, ….. I_n respective instantaneous currents through them.
• These branches have instantaneous voltages across them are V₁, V₂, V₃, ….. V_n respectively.
• According to Tellegen’s theorem, \(\mathop \sum \limits_{k = 1}^n {V_k}.{I_k} = 0\)
• It is based on the conservation of energy.
