Engineering Circuit Analysis: Vol 1 – Section 1
Introduction to the Node Voltage Method

In this lesson, we begin to study a more advanced solution method
for circuits known as the Node Voltage Method. This method is ultimately
easier to solve for most circuits because it requires less equations to be written.
We explain the technique and provide a step-by-step example to give the
student a solid foundation. Subsequent sections will solve problems of
increasing complexity with the Node Voltage method.

HP50g – Lesson 21 – Working with Complex Numbers

In this section, you will learn how to enter and perform computations that
involve complex numbers. Complex numbers are numbers that have a real
and imaginary part and are used in every branch of math, science, and
engineering. We’ll learn how to enter complex numbers in rectangular form
and polar form, learn how to convert between these forms, and how to
perform math operations.

In this science video, you’ll learn how to build a simple battery out of a lemon
and other household materials!  We’ll use this battery to power an electronic
calculator!

I’ve posted the first in a series of science experiments that will teach anyone
about how science is all around us.  In this first video, I show how to construct
a simple electric motor out of a magnet, a screw, and a battery.  It literally takes
a minute to build!

Solving Circuits with Kirchhoff’s Laws – Part4

In this lesson, we continue to use Kirchhoff’s Voltage Law and
Kirchhoff’s Current Law to solve circuit problems. In this problem,
we are asked to find the currents in two different legs of the circuit
and the voltage drop across the constant current source.

In this lesson, we continue to use Kirchhoff’s Current Law and
Kirchhoff’s Voltage law to solve circuit problems.

Circuit Analysis: Volume 1 – Lesson 7
Solving Circuits with Kirchhoff’s Laws – Part 1

In this lesson, we use the knowledge and skills gained with Kirchhoff’s
Current Law and Voltage Law to solve circuits. In these problems, we
will need to write one or more equations involving Kirchhoff’s Laws and
solve the equations to find the currents and voltages in the circuit.
