AC PCB Repairing Course Pull Up & Pull Down Resistor का Use क्यों किया जाता है? Pull Up और Pull Down Resistor का इस्तेमाल Logic Signal को Stable करने के लिए किया जाता है। Pull Up Resistor: Signal को High (1) Logic पर Fix रखता है जब तक Input Active न हो। Pull Down Resistor: Signal को Low (0) Logic पर Fix रखता है जब तक Input Active न हो। अगर ये Resistor न लगाए जाएँ तो PCB में Logic Floating हो जाता है और Circuit गलत काम करने लगता है। Multitech Institute में आपको practically सिखाया जाता है कि Pull

When you put a resistor, an inductor, and a capacitor together in a series circuit — what we call an LCR circuit — something interesting happens: the current and the voltage don’t always rise and fall at the same time. This timing difference is what we call the phase difference. Here’s the picture: ✔️In a resistor, current and voltage are perfectly in step. They climb and drop together. ✔️In an inductor, the voltage is always a bit ahead, while the current is trying to catch up. ✔️In a capacitor
