  1. Introduction

    Learn about Symbulator and how it can help you focus on learning how circuits work, instead of struggling with math. Get the latest version of Symbulator and get ready to roll.

  2. Lesson 1

    Direct current analysis

    Learn to describe a circuit in Symbulator, and how to run a direct current analysis using dc. Learn how to describe a voltage source using e, and a resistor (or a conductance) using r.

  3. Lesson 2

    Symbolic circuits and expert mode

    Learn how to solve different types of symbolic circuits in Symbulator. Use the solve command on Symbulator answers. And explore ex, the powerful expert mode, for the ambitious user.

  4. Lesson 3

    Current sources, conductances and dependent sources

    Learn how to describe a current source using the j element. Simplify parallel resistors using the pr tool and its shorthand. Learn to describe conductances and dependent sources.

  5. Lesson 4

    Shorts, equivalent resistance and Thévenin/Norton

    Learn how to describe a short circuit using the s element. Learn how to find equivalent resistances using the er script, and Thevenin and Norton equivalents using the th script.

  6. Lesson 5

    Operational amplifiers

    Learn how to describe an ideal operational amplifier (Op Amp) using the o element. And practice what you learn in a variety of solved op-amp problems, both easy and hard.

  7. Lesson 6

    Transient analysis

    Learn to run a transient time-domain analysis with tr. Learn to describe capacitors with c and inductors with l. Save time with the only tool. Plot expressions in time with the plot tool.

  8. Lesson 7

    Alternating current analysis

    Learn how to run an alternating current analysis (via phasor analysis) using ac. Learn how to describe capacitors, inductors, impedances and admittances, and sources for AC analysis.

  9. Lesson 8

    Power in AC circuits

    Learn to solve average power and complex power problems in AC. Learn how you can use RMS values in Symbulator with the rms flag. Solve power factor problems using the pf tool.

  10. Lesson 9

    Three-phase circuits

    Learn to solve simple three-phase circuits in Y-Y, Y-Δ, Δ-Δ and Δ-Y configurations, both balanced and unbalanced, to find line and phase currents, voltages and complex power.

  11. Lesson 10

    Mutual inductance and ideal transformers

    Learn how to describe a mutual inductance between two inductors or two impedances using the m element. Learn how to describe an ideal transformer using the t element.

  12. Lesson 11

    Bode plots and resonance

    Learn to do gain and phase Bode plots for transfer functions of ω and s with the bode tool. Find the resonant frequency of an answer by solving for the frequency at which the reactance vanishes.

  13. Lesson 12

    The complex frequency domain

    Learn to solve complex-frequency domain problems using fd. Move between the time domain and the s-domain with the t2s and s2t shortcuts. Learn to solve transfer function problems.

  14. Lesson 13

    Two-ports

    Find the two-port equivalent of a network using the port script. Learn how to include two-ports in your circuit using the z, y, h, g, a and b elements. Calculate gains with the gain tool.
