for Jao 2 LED Blinker PNP DC

In these circuit it will show how the other component changes affects how the LEDs light up. If we add to much values on resistor for example we used a 1k Ω on Resistors it will make the light blur and makes the light lesser, while if you adjust it to lower Ohms (Ω), like 100 Ω it will cause the LEDs to explode. It’s because the LEDs cannot contain more voltage than its limit. So by using the Resistors before the current flows to the LEDs, it can minimize or limit the voltage so the light will be maintained. And thus the Resistor changes and limits the current voltage that will surge to the LEDs, the other component like Transistor and Capacitor Changes the flow of current and how much voltage will flow to a circuit series cycle. By changing the flow of Transistor from left to right might change the output of the LEDs because the capacitor changes where the voltage pumps the voltage higher so by not putting a resistor after it before a LED might cause the LED to explode or might make it won’t even light at all. On the other hand, Capacitor stores the energy when the current flows to it then release slowly release it throughout the circuit. This controls how fast the current will flow and how fast the positive flow changes to negative. By changing the voltage and capacity of the capacitor can change and affect how fast the light of the LEDs turn on and off. It can change the speed of alternate blinking of LEDs in this experiment.
