Pull-up & Pull-down Resistors

In understanding how pull-up and pull-down resistors work for microcontroller inputs, and why they’re necessary, it’s important to see a circuit diagram. Unfortunately, most circuit diagrams on the Internet are somewhat incomplete — that is, they’re usually missing the microcontroller along with its input impedance (resistance) and ground. 911 more words


Watts, Volts, Amps and Ohms!

Voltage is related to potential-energy difference. The voltage drop across any circuit element is directly proportional to the change in energy of a charge as it traverses the circuit element. 209 more words

Basics of Resistors. Design Note 5

For a Beginner, identification of Resistors is a big problem. So byhearting the Colour code is essential. But some tricks are available to identify the resistors easily. 416 more words

Rangkaian RL arus searah

Bentuk rangkaian RL ditunjukkan Gambar 1. Pada umumnya induktor terbuat dari lilitan kawat sehingga sulit untuk mendapatkan induktor murni yang hanya memiliki nilai induktasi sebab induktor murni memiliki resistansi sama dengan nol. 232 more words
