Why does a current source present a challenge for the mesh current method?
Question: 1). Why does a current source present a challenge for the mesh-current method? because the voltage change across a current source cannot be written in terms of resistances as usual B). because choosing the wrong value for the current source will lead to an erroneous solution C).
Can you do Mesh current Analysis with a current source?
1 Answer. You don’t need meshes. Just calculate everything one source at a time, while keeping the other sources zeroed out (i.e. a voltage source is replaced with a wire, and a current source is replaced with an open (cut) circuit). Then sum the results from each source.
Which is the electrical equivalent of Thevenin equivalent circuit?
The “Thevenin Equivalent Circuit” is the electrical equivalent of B1, R1, R3, and B2 as seen from the two points where our load resistor (R2) connects.
How to calculate the equivalent of Thevenin’s theorem?
Calculating the equivalent Thevenin source voltage and series resistance is actually quite easy. First, the chosen load resistor is removed from the original circuit, replaced with a break (open circuit): Next, the voltage between the two points where the load resistor used to be attached is determined.
Which is the equivalent of the Thevenin resistance?
This is our “Thevenin resistance” (R Thevenin) for the equivalent circuit: With the load resistor (2 Ω) attached between the connection points, we can determine the voltage across it and current through it as though the whole network were nothing more than a simple series circuit:
Which is an advantage of performing the Thevenin conversion?
The advantage in performing the “Thevenin conversion” to the simpler circuit, of course, is that it makes load voltage and load current so much easier to solve than in the original network. Calculating the equivalent Thevenin source voltage and series resistance is actually quite easy.
