Set a specific learning goal, work towards it with a deliberate plan, then honestly assess whether you achieved it and what you would change

Electronics // Circuits

Electricity flows only around an unbroken loop from one side of a power source, through components, and back to the other side. A switch works by opening and…

Electronics // Circuits

Voltage is the push from the source, current is how much charge flows each second, and resistance is how strongly a component limits that flow. Turning up the…

Electronics // Circuits

For a resistor, voltage equals current times resistance (V = I × R). Rearranging it gives the current a circuit will draw or the resistor a part needs.

Electronics // Components

An LED lights when current flows through it one way, from the longer leg to the shorter. It needs a resistor in series so the current stays small enough not to…
