Diode or P-channel MOSFET is what you need to protect your circuit from applying reversed voltage, according to a nice video published on Afrotechmods channel. Method 1:Diode The simplest way is to use a diode in series with main power supply. When you connect the power source right, the diode anode is connected to positive […]

“baldengineer” explains which way the current flows. A couple of weeks ago I wrote about four current flow direction myths. As a follow up to that popular post, I decided to dedicate this month’s AddOhms electronics tutorial video to Current Flow. In episode #19, I tackle the question of which way does current flow. You […]
