Circuit Basics 2 – Ohm’s and Joule’s Laws

By | 2017-08-04T13:50:58+00:00 July 25th, 2017|0 Comments

Now that we have introduced some electrical properties like voltage, current, and resistance we need to understand how they relate to each other. Amazingly, most electrical properties relate to each other in ways that are beautifully simple.   Ohm's Law All of the electronics begins with one simple equation called Ohm's Law. Georg Simon Ohm was [...]

What are Voltage Regulators, and How Do I Use Them?

By | 2017-07-25T15:40:02+00:00 July 20th, 2017|0 Comments

An STMicro Through-Hole Linear Voltage Regulator Voltage regulators are circuits (often Integrated Circuits or ICs) that maintain a constant output voltage level. Voltage regulators, of some kind, are used in many of the electronic devices around us. This is why many of them can accept a range of input voltages or use one [...]

Through-Hole LEDs in Various Colors A light-emitting diode or LED, is, in fact, a diode. An LED has all of the characteristics and properties of a normal diode with the addition of emitting light. Being a diode, the power flowing through an LED only experiences a voltage drop with very little resistance. Consequently, [...]

Relay Soldered to a Breakout Board A relay is a switch that is actuated by an electromagnetic coil. One side of a relay is simply a switch made of electrical contacts and a metal reed that naturally rests in an open position. The other side of the relay is an electromagnetic coil. When [...]

Circuit Analysis – Kirchhoff’s Laws

By | 2017-08-04T13:52:37+00:00 July 20th, 2017|0 Comments

Gustav Kirchhoff was a physicist who defined two laws that are paramount in our understanding of electrical circuits.   Kirchoff's Current Law (KCL) Kirchhoff's first law deals with nodes in a circuit. It says that the algebraic sum of all current entering a node in a circuit is zero. We have to specify that it is the [...]

What are Transistors and How Do I Use Them?

By | 2017-07-25T15:12:25+00:00 July 20th, 2017|0 Comments

Two Through-Hole Transistors next to a SMT Transistor Transistors are electrical components that amplify small signals into big signals. They take a small amount of power and release a large amount of power. The transistor functions like an aerosol can;  small amount of force on the nozzle can release lots of energy. Transistors are constructed [...]
