Lab 1 Task 2 IV Curves of R and D in LTspice

This video tutorial covers Task 2 in Lab 1, focusing on simulations using LTSPICE. It begins with an introduction to the task and explains transient simulation, including setting initial conditions for capacitors. The tutorial then demonstrates how to obtain the IV curve for a resistor by sweeping voltage and using different simulation commands. Finally, it shows how to replace a resistor with a diode to obtain its IV curve, highlighting the differences between various types of diodes.
