⭐️ Check out our website https://www.cognito.org/ ⭐️ *** WHAT'S COVERED *** 1. An introduction to electrical circuits. * How to draw simple circuit diagrams. * The standard symbols for common circuit components like cells, batteries, lamps, and switches. 2. An explanation of the three key electrical quantities. * What potential difference (voltage) is and how it drives the current. * What electric current is and how it is measured. * What electrical resistance is and how it opposes the current. 3. The direction of current in a circuit. * The difference between the actual flow of electrons and conventional current. * How to identify the positive and negative terminals on a cell or battery symbol. *** CHAPTERS *** 0:00 Introduction to Electric Circuits 0:26 What is a simple circuit diagram? 0:46 Standard symbols for circuit components (cell, battery, lamp, switch) 1:49 Explaining Potential Difference, Current, and Resistance 1:58 What is electric current?
