Homework Statement
Find the impedance as seen by the source.
Homework Equations
The Attempt at a Solution
-j2||j1 = 2i
Z = 2-j1+j2+(1^2)/(j2+2+j2)
Ztotal = 2.1+0.8i
Is this correct?
Mutual inductance?NascentOxygen said:What do you understand is meant by the j2 Ω on each side of the transformer? What does the j1 Ω referring to both sides indicate?
Well, I don't know the direct formula for finding impedance in such coupled circuits, but you can use mesh analysis on both the sides and find the current on the source side. Source voltage/source current will be the impedance seen by the source.eehelp150 said:Mutual inductance?
The final result looks okay, but whether or not your work is correct is hard to say. Since all the values in the circuit are 1's and 2's, they become somewhat anonymous when we can only see digits.eehelp150 said:Homework Statement

The Relevant equations part of the template is there for a good reason. Could you not have quoted or referenced the equation that you employed?

Impedance seen by source refers to the total impedance that a source experiences when connected to a load. It takes into account the internal impedance of the source and the impedance of the load, as well as any other components in the circuit.
To calculate the impedance seen by source, you need to add the internal impedance of the source and the impedance of the load. If there are any other components in the circuit, their impedance should also be included in the calculation. The resulting value is the total impedance seen by the source.
Impedance seen by source is important because it determines the amount of current that can flow through a circuit. If the impedance seen by source is too high, it can limit the amount of current that can be delivered to the load, resulting in reduced performance or malfunction of the circuit.
Impedance seen by source is an important factor to consider in circuit design. It can affect the choice of components and the overall performance of the circuit. Designers aim to minimize the impedance seen by source to ensure efficient and reliable circuit operation.
The impedance seen by source can be controlled by using components such as resistors, capacitors, and inductors in the circuit. These components can be used to adjust the impedance and ensure that it is within the desired range for optimal circuit performance.
