Electricity and Electronics Courses - Khan Academy Help Center I've spent 35 years in IT but I now realise I'm lacking electrical and electronic skills to try and trace or repair faults or power on issues So I want to start studying Electrical and Electronics Courses so that I can trouble-shoot issues
Basic electrical quantities: current, voltage, power Voltage and current are the cornerstone concepts in electricity We will create our first mental models for these basic electrical quantities We will also talk about power, which is what happens when voltage and current act together
Conductors and insulators (video) | Khan Academy A conductor is a material that allows electrons to flow freely through it, making it useful for carrying electric current An insulatoris a material that resists the flow of electrons, so it does not allow electric current to pass through it Learn about how conductors and insulators work and how they are effected by changes in electrical current
Khan Academy Oops Something went wrong Please try again Uh oh, it looks like we ran into an error You need to refresh If this problem persists, tell us
Circuit elements: Capacitors in electrocardiography monitors Nodes are attached to a patient’s skin, which in turn is able to pick up cardiac electrical activity These nodes then relay this information to the main monitor, which displays it accordingly A technician is working at a hospital with similar machines, referred to as electrocardiography (ECG) monitors
Science | Khan Academy Electrical engineering Learn about electricity, circuit theory, and introductory electronics We also have sections that let you get down and dirty with household items, from building your own robot to videos where we disassemble household items to see what's inside
