Welcome to Introduction to Electronics.

I'm Dr. Robinson.

In this lesson I wanted to give

you a quick overview of things to

come in this course.

Now there's really no need for

me to motivate electronics to you.

You couldn't be watching this

video without electronics and

electronic devices.

And you wouldn't have available to you all

the technology that you use every day.

Now, the particular devices that

we are going to study in this

course are the diode, the transistor and

the operational amplifier.

The diode and

transistor, can truly be considered

to be fundamental electronic devices.

While the op amp is a more

complicated device,

that's composed of the more

fundamental devices.

Now as we proceed through the course

we will study the operation of

these electronic devices.

And we will also study particular

application circuits which

use the devices to achieve

some functionality.

And you can consider these application

circuits to be building blocks which can

be combined together to form

more complicated circuits.

Now we begin this course with a review

of topics from linear circuits.

We then move to a module on operational

amplifiers followed by one on diodes and

we conclude with a module on transistors.

Now at the end of this course you

should understand the operation of

these fundamental devices.

And you will have available to you

techniques that you can use to

analyze more complicated circuits.

And overall this course will

give you a good foundation for

the further study of electronics.

So, thank you for taking this course,

I hope you enjoy it.

And I will see you in future lessons.

Welcome to the introduction

to electronics.

I'm Dr. Ferri and this lesson will

be a review of circuit elements, and

actually the next few

lessons will be a review,

of basic circuit type principles

that you're expected to

know before you come into an electronics

class, so they cover linear circuit.

Principles, so if you want to review

these lessons, you're welcome to do it.

If you want to skip them because you're

very familiar with circuit element,

linear circuit elements,

then you're free to do that as well.

In the previous lesson,

we covered the physics of MOSFETs.

In this lesson, we will review resistors,

capacitors, and inductors, and

their current voltage characteristics,

as well as looking at sources and nodes.

So let's look at these passive elements.

A resistor, a capacitor, and an inductor.

In each of these cases.

We show by convention that the current is

going into the plat, the positive side

of the voltage, and with that sort

of convention we get the equation.

So this equation corresponds to

this convention where this arrow is

flowing into the positive side.

And this particular equation

is called Ohm's Law.

The voltage is equal to

current times the resistance.

The resistance is measured in ohms.

And the symbol is.

And omega.

Now if I go on to a capacitor,

capacitor is an energy storing device.

And it has,

it is governed by this differential

relationship between the current through

the capacitor and the voltage across it.

And note again that the convention

is to show the current going into

the plus side of the voltage and

then we get this equation.

The, the units on

capacitors are farads and

usually we'll, we'll be looking at units

that are in 10 to the minus 6 farads

or represented as micro farads.

Those are common, more commonly seen.

Then we get to inductors.
