Thankyou sir
You're welcome
Thanks for the great guide sir. What are the most common real life uses for CE?
It's widely used in audio applications, ex. Sterio and Amplifier 📢
Hi, sir. Can you plz explain why the voltage drop across RE was not considered when you wrote VCE = Vplus - IC*RC?
At higher frequencies, RE gets bypassed or shorted by the capacitor CE
Why on earth would you use exponents for resister/cap values??? why lolol

In SPICE, resistor values are typically specified in ohms (Ω), and the notation "500e6" would represent a resistor value of 500,000,000 ohms, or 500 megaohms. While SPICE itself doesn't inherently limit the range of resistor values that can be used, practical considerations such as model accuracy, simulation stability, and component availability may affect the feasibility of using such high resistance values in a circuit simulation.
For very high resistance values like 500 megaohms, factors such as parasitic capacitance, leakage currents, and model accuracy become significant. SPICE models for high-value resistors may not accurately capture these effects, leading to discrepancies between simulation results and real-world behavior.
Furthermore, in practical circuit design, sourcing resistors with extremely high values might be challenging or costly due to manufacturing limitations and material properties.
It's essential to consider these factors and consult the documentation of your specific SPICE simulator and resistor models to determine the feasibility and accuracy of using such high resistance values in your simulations.
@@stemscience1 That's not what I'm talking about. SPICE has a system to simplify the values to real part specs specified in the model, aka "10e3" is "1k" and vice versa. Using exponents to denote a component value is 100% an anti-pattern in circuit modeling but always very hard to read. You would never read a real schematic with SI notation for values. You also use that notation for capacitors which is inconsistent and weird. I watched the video looking for a reason to use them but it's just sort of arbitrary.
Why does SPICE then allows to use exponent?
