Total impedance in primary side of transformer
Consider an ideal transformer with load connected (simple ideal case for simplicity).
So I learnt about reflected impedance Z2'=a²Z2 (in terms of secondary impedance reflected on the primary).
My ...

How do I apply block reduction techniques to the following block diagram
The question prompt is to find a final transfer function Y(s)/R(s) for the below block diagram, and then to find the time domain version of it by taking the Inverse Laplace.
My professor recommended ...

Resistors in series or in parallel? [duplicate]
I'm having trouble understanding why R1 and R2 as well as R3 and R4 are in parallel and not in series. I thought that because the circuit is open circuited at the ends, that no current flows into ...

How to find the RMS value of a triangular function (homework)?
I have no idea where I went wrong with this homework question:
The waveform:
I deduced the function as:
$$
y=\begin{cases}
1000t & t\in [ 0,0.002]\\
-1000t+4 & t\in [ 0.002,0.006]\\
1000t-8 &...

Solving for equivalent resistance and flow of current
Equivalent resistance between terminal A & N is 2.44 \$\Omega\$ (answer key).
Instinctively I tried to find it by assuming 4\$\Omega\$, (5+6)\$\Omega\$, (10+5)\$\Omega\$ were in parallel as they ...

How is there any small-signal gain?
I am not sure if I am approaching this wrong. I don't see how there could be any small signal gain because isn't Vo tied to AC ground since M3's current will not fluctuate with change in Vi?

Kirchoff's Voltage Law in this mesh
I found the following results using nodal analysis and confirmed them via mesh analysis:
The voltage across the 2\$\Omega\$ resistor is -4\$\text{V}\$.
\$I_3 = 3\,\text{A}\$ and \$I_2 = -2\,\text{A}\$...
