The total power developed in the circuit, if V­_o = 125 V is

Concept:

• 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, ….. In respective instantaneous currents through them.
• These branches have instantaneous voltages across them are V1, V2, V3, ….. Vn 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.
• It is applicable to both linear and non-linear circuits.

Analysis:

By applying Tellegen's theorem we can see that the net power developed in the circuit of the question = 0 watt
