### Conceptual understanding of phase power vs. line power

I am looking at two formulas: P = √3 x VL x IL x Cos Ф P = 3 x VPh x IPh x Cos Ф Now assuming P here refers here to the total power. Could I take VPh and IPh and combine those terms as P (Phase)? Same ...

### Nodal Analysis of an Inverting Operational Amplifier

I am trying to derive the closed-loop gain of a basic Inverting Op-Amp circuit using nodal analysis and the model that includes its non-ideal parameters. The equation I derived is incorrect, and it's ...

### Confusion understanding a half adder implementation using 74153 MUX [closed]

As shown here, I have also highlighted the confusing part in the attached snapshot. In the last line of truth table, I know that sum is equal to XOR of two inputs, but here in the last line of the ...

### Analysis circuit using Thevenin theorem

in the book "Engineering Circuit Analysis", example 5.9, i don't understand few things, hope someone can clear up for me: Why does the dependent current can't flow through resistor 3k? If ...

### Design of power input protection on NVIDIA Jetson Xavier NX (dev kit)

When looking at the schematics of NVIDIA Jetson Xavier NX developer kit, they use a P-channel MOSFET (AONR21357) before bringing power to a buck converter (TPS53015, not represented below). What is ...

### How to Calculate Voltage across R2 for any Value of R1, R2, and Frequency?

I know this is really simple, but I'm really new to electronics, so please bear with me. CircuitLab said that the voltage across R2 was -14.24 dbV, given the component values shown and a source ...

### What is the difference between large signal model/analysis and dc model/analysis? [closed]

I am studying microelectronics. I have studied about the DC analysis and the AC analysis. The DC analysis is just to find the operating point or the quiescent point and then the AC analysis is done. ...

### Frequency domain analysis when sampling a switched (gated) integrator

I would like to use AC analysis (e.g. in spice) on a non-ideal op-amp integrator where the reset switch is open, and then apply a shaping function to the result of the AC simulation (in the frequency ...

### Effects of decreasing the field voltage of a synchronous machine

I am running a simulation of a synchronous machine in matlab and I have some behaviour I cant quite grasp my head around. The machine is running as a motor with only about 20% of its maximum load, ...
