Capacitive impedance is the ratio of phasor voltage to phasor current in a capacitor. It also means the opposition of a capacitor to an alternating current. Impedance of a capacitor is dependent on the frequency of the voltage or current across it.

Light dimmer circuit projects are a good way to learn about thyristors. Thyristors, which include TRIAC, SCR, and Shockley diodes, are four-layer semiconductors that find many applications in AC power control. This post will show you how to create a light dimmer circuit with a TRIAC. As an additional feature, …

Analog to Digital Conversion Overview Microcontrollers are essentially computers. And like computers, they only understand two numbers: a 1 and a 0. So when a microcontoller needs to read a quantity with varying numbers in a period of time (a.k.a. analog), an analog-to-digital conversion is necessary. An ADC (analog-to-digital) converter …

Introduction to Voltage Dividers Resistors are in series when the same current flows through them. Consequently, by Ohm’s Law, the total voltage in a circuit of series resistors is the sum of the individual drops on the resistors. Another way of saying this is that each resistor contributes to the …
