This is a simple flashing led circuit with 2 leds and 2 NPN transistors ... It’s state is constantly changing and this change affect the flow of current and voltage and the effect will be visible with ...

LEDs, like batteries, have polarity, which means that there is a specific direction that current must flow through them: it must enter through the positive lead and exit through the negative lead in ...

While LEDs are common in voltage detection applications, I have never seen an LED circuit that is dedicated to indicating the presence of low values of current flow. This simple LED current sensor ...

Removing either LED does not break the circuit, either, because current can still flow through the other LED to complete the circuit. In a parallel circuit, all the LEDs you connect will glow no ...

The voltage across the string increases with each LED added ... will drop and less current will flow through the other strings (Eq. 6). A power-limit circuit can be added to the circuit in ...
