Hello 2 all !
I am a student on electrical engineering, and i have the following problem to solve:
An electrical circuit includes a dc voltage source with an internal
resistance, and a load resistance. Determine the value of the load resistance R (with a precizion of 0.1 Ω) for which the power delivered by the source will be maximum, knowing that U = 12V and rs = 2.5 Ω.
If i understand the problem correctly, the maximum power transfer occurs when the load resistance value equals the internal resistance of the source.
Is this not correct ?
Why am i asked to calculate the load resistance with a precision of 0.1 Ω ?
Is there something that i am missing here ?
I am attaching the circuit schematic as a reference.
Thank you very much for taking the time to answer my question.
