3/8 Mesh Current Method

We are introduced to the idea of a supernode that exists when a voltage source exists between two nodes. We can say that the potential difference between the nodes surrounding the supernode is the same as the voltage from the supernode and makes it easier when calculating for the different currents in the circuit.

We are given a circuit problem with givens and asked to identify each current and voltage in the circuit by using the mesh current method.

From the same problem, we are told that each resistor can be increased and decreased by 10% and asked to find the different currents in the circuit when the resistors are +10% and -10%.

Rather than calculating by hand the different current values 3 different times from the equations, we plug in the equations and values into MATLAB to solve the system of equations.

Here we have a circuit where we use the mesh current method of finding the different currents in the circuit.

This is the circuit from before put into the breadboard.

We used a website called EveryCircuit and calculated the theoretical values of the circuit and found them to match our calculations.

Here we are given resistors and asked to determine its resistivity based on its color code.
