How the final Project Countdown circuit worksAs the capacitor is being filled, the current reduces through the resistors. The last resistor runs out of current first, and that turns off the PNP which makes the LED turn on. The resistor behind the one that ran out of current runs out of current next, and finally the 1st resistor runs out when the capacitor is filled.
Capacitors In A Circuit - Small Capacitorwhen you replace the larger capacitor with the smaller one, the LED doesn't fade that much because it can't hold as much electricity
About the PNP Circuitit needs power to not come in to the base prong to work, and so when our tentacles are connected it does not go off
Why can't we see infrared?we can not see infrared because that is the only type of light energy that our eyes are not sensitive to.
Why the LED stayed offThe LED stayed off because the thermistor is at room temperature, and the circuit is not set up so the LED turns on when it gets warm. The circuit is set up so when the thermistor is cold the bi-color LED will turn on, not the other way around.
PNP Transistor ReviewIf the base prong is connected to the negative battery wire, it will be turned off, lighting up the LED. If the base prong is connected to the positive battery wire, the transistor will be on, turning off the LED.
