[2015] Saikishore Gowrishankar: Circuits

What is a circuit?A circuit is a path created so that electrons can flow through it to accomplish a specific task, such as powering an LED. Electrons tend to move from an area of high to low voltage (voltage is described in the diagram above).

Another example of electronic circuits are Printed Circuit Boards, or PCBs. These are commonly used in electronic devices and systems that need to perform complex tasks and have many electronic components, resistors and capacitors.

The Science Behind it!

This chart shows the common mathematical formulas to calculate Resistance, Current, Voltage, and Power (power supply) based on certain values. Resistance is calculated using Ohms, a measurement used to calculate resistance.

Printed Circuit Boards

Any circuit that does not form a fully closed loop is known as an open circuit. If it does form a full loop and electrons flow, it is a closed circuit.

Electricity is known as the movement of electrons. This movement creates electrical charge, which can be measured in 3 ways:--Resistance - Makes it hard for current to flow through a material because of the material's characteristics.--Current - The rate at which electric charge flows.--Voltage- A measurement that shows the difference in charge between two points

Open/Closed Circuits

Resistors will control the amount of energy released for desired effects (like brightness control on a phone), and capacitors will store energy (like a battery) for rapid discharging. An example is a short burst of light like a camera flash.


Electrical Charge

A short circuit occurs when a circuit has a lower resistance than a regular circuit and can lead to contact where you don't want it! Make sure to address these problems when working with circuitry
