Maximum Power Transfer Thevenin. In dc circuit the impedance of circuit is equal to the resistance. Various resistors 100 ω 330 ω 470 ω 1 kω and 15 kω procedure.
119 a to the left of the 10 ω resistor by its thevenins equivalent circuit gives us a practical voltage source with vth 21 v and rth 5 ω. Simply stated the maximum amount of power will be dissipated by a load resistance when that load resistance is equal to the thevenin norton resistance of the network supplying the power. This famous result is termed the maximum power transfer theorem.
Objective the objective of this laboratory exercise is to verify the validity of thevenins theorem via comparison of experimental and theoretical results.
Maximum power transfer theorem states that the dc voltage source will deliver maximum power to the variable load resistor only when the load resistance is equal to the source resistance. This means that the load impedance is the complex conjugate of the source impedance. Similarly maximum power transfer theorem states that the ac voltage source will deliver maximum power to the variable complex load only when the load impedance is equal to the complex conjugate of source impedance. Explanation of maximum power transfer theorem.
