Stages of DIY electronics design
You get an idea! Prototype Schematic +PCB design
PCB Manufacture
What we’re making
Electric circuit
“An electric circuit is formed when a conductive path is created to allow free electrons to continuously move. This continuous movement of free electrons through the conductors of a circuit is called a current, and it is often referred to in terms of "flow," just like the flow of a liquid through a hollow pipe.
The force motivating electrons to "flow" in a circuit is called voltage. “http://www.allaboutcircuits.com/vol_1/chpt_2/1.html
Electricity
Resistance, Voltage, Current
Resistance
Resistance is the hindrance to the flow of charge.
Voltage
Voltage is the force or pressure that excites the electrons to flow.
Current
Current is the rate of the electrical charge passing through a point on a circuit, measured as a quantity over time.
