### Output current of full-bridge rectifier with LC filter

Now that you've selected an answer and I won't be treading on anyone's feet, I can write more freely than before. Whether or not you'll see it is another matter. There's a reason why Andy's equation ...

### Output current of full-bridge rectifier with LC filter

If my method to find out the output current IR is incorrect, how can I find it by hand, without simulator? Once you have full-wave rectified the output and then used a 2nd-order low-pass filter to ...

### Equivalent electrical circuit changing and power balance calculation

Find your coloured pencils or felt-tip pens or crayons and, superimpose a coloured line on the node that is to the left of R2. Then, in a different colour mark the node on the right of R2. Then, do ...

### Input resistance of an inverter op-amp circuit

I need to find the input resistance of this circuit. Do I make it by finding the equivalent impedance of R3, R4, C and R5? It's slightly simpler than that. Because the -Vin input is a virtual ground, ...

### Is RC frequency response related to series RC or parallel RC?

It is correct that the principle topology of both circuits is comparable (neglecting the minus sign at the moment). However, there is a huge difference if we consider the values of the components and ...

### Can a series RLC circuit have an unstable natural response?

Interesting discussion. Shows not to trust books! Not only bodged the algebra, but confusing the Laplace transform with the Laplace transfer function. Going back to the question: Is it ever possible ...

### What is Vac(peak) in this question?

Given that 230V RMS is common in Europe, and the question refers to "AC supply" making me think of domestic mains, I'm sure that $v_{AC}$ is the RMS value of 230V, where peaks would be ±...

### I designed a PCB around the IP5328P powerbank SoC and it is not working. Why?

Maybe the problem is the VSYS net. In the circuit diagramm I see no connection from pad 8,9 to pad 22, 23, but this connection is required.
