In a triac phase control circuit, the triac is triggered ON only for specific portions of the AC half cycles, causing the load to operate only for that period of the AC waveform. This results in a controlled supply of power to the load. Triacs are popularly used as a solid-state replacement of relay for […]

LM10 Op Amp Application Circuits – Works with 1.1 V
The LM10 is a pioneering operational amplifier designed to operate from single ended power inputs with voltages as low as 1.1V, and up to as high as 40V. As can be witnessed in Figure 1, the device consists of an op amp, a precision 200 mV band-gap voltage reference, and a reference amplifier, all encased […]
How RC Circuits Work
In an RC circuit, a combination or R (resistor) and C (capacitor) is used in specific configurations in order to regulate the flow of current, for implementing a desired condition. One of the main uses of a capacitor is in the form of a coupling unit which allows AC to pass but blocks DC. In […]
