What is wrong with this PSpice simulation?

I am trying to simulate this circuit on PSpice as my first PSpice homework, I’m required to learn to simulate circuits on this software. From calculations, we know that: Ix = 16 A. Current through 20 V source is 6 A. Voltage across VCCS is 12 V. Voltage across the CCVS is 8 V. 20…

Find Id of NMOS

I need to find the drain current in the above circuit where I also know VTH=1VVTH=1VV_{TH} = 1\,\mathrm{V} and μnCox=2⋅10−4AV2μnCox=2⋅10−4AV2\mu_{n}C_{ox} = 2\cdot 10^{-4} \frac{\mathrm{A}}{\mathrm{V}^2}. I’m just not sure about how to find VGSVGSV_{GS} in this circuit. I’m used to using voltage dividers. =================      As a heads-up, when a transistor is connected in this…

What are the bare minimum parts needed to operate a magnetron?

I recently took apart a microwave, and I managed to get a magnetron out of it, as well as a transformer that appears to be the power source for the magnetron, but looks a little small for the advertised amount of power this magnetron can handle (~1 kW). Also, the magnetron does not have any…

Finding transfer function of this RL circuit

Have a look at this circuit. I am to find the transfer function which is defined as VL(s)/V(s)V_L(s)/V(s). Now I don’t understand the solution. First of all, it defines VL(s)V_L(s) at the bottom as sI2(s)sI_2(s). Shouldn’t it be 2sI2(s)2sI_2(s)? Also, shouldn’t the transfer function be 1/[s+3+(1/s)]1/[s + 3 + (1/s)]? Here’s how I came to…

Applying KVL to this circuit

In my Circuit Analysis book, I am tasked with finding vxvxv_x and vyvyv_y. So vyvyv_y: easy enough. It’s – 6 volts. But I encounter a problem when trying to find vxvxv_x – I can’t develop enough independent equations to solve for all of the elements in a given loop. Of the components in series, I…

Convert a non-isolated converter to an isolated converter

Is there a way to convert a non-isolated converter(such as R-78C5.0-1.0) to an isolated converter. ================= ================= 1 Answer 1 ================= No, there is no practical way. If you can use a transformer isolated supply on the input it will be isolated (by the transformer).      Thanks Spehro. You are ubiquitous. I figured I…

Missing steps to simplify this complex impedance

The problem is: How would you you simplify the equation to get down to 716.97−j450.47Ω716.97 – j450.47\Omega? I tried multiplying by the conjugate but that doesn’t work. =================      I’m getting 716.97+j450.47Ω716.97 + j450.47\Omega by multiplying the numerator and denominator by the complex conjugate of the denominator. I think the imaginary part should be…

voltage drop alternative to resistor [duplicate]

This question already has an answer here: Reducing voltage with resistors 6 answers My application requires me to drop voltage from 12v to 6v or any other lower voltage. I have used resistors but they are not efficient for prolonged use as they tend to heat up and burn my fuse. I want to know…

Potential difference in a capacitor

As I simulated the circuit below, it shows that the potential difference across Cx is the amount of potential being stored on C3 and C4 during charging phase. How do we get the potential difference of a capacitor? And how did this happen? What theory is behind this operation? =================      Can you ask…
