How To Calculate and Connect LEDs in Series and Parallel
In this article I have explained how to calculate LEDs in series and parallel using a simple formula and configure your own personalized LED displays, now you don’t just have to wonder how to wire led lights? but actually can do it, know the details here. These lights are known not only for their dazzling […]
How to Connect Resistors in Series and Parallel
There are three ways to interconnect resistors: series, parallel and in combination of series/parallel. When resistors are joined in series, the current passing via one resistor also passes through the next. When resistors are joined in parallel, they are wired across each other, resulting in the same voltage across each resistor. When resistors are connected […]
How to Calculate Capacitors in Series and Parallel
Capacitors connected in series or parallel are very common in electronic circuits. This is done in order to achieve the desired capacitance value and also to make the performance of the circuit accurate. In the following post I have explained how to connect capacitors in series and parallel: Connecting Capacitors in Series When we connect […]
Standard Resistor E-series Values
The resistor’s values which are provided to them fall within a category of standard or preferred resistor values. By: S. Prakash The values present within the standard resistor category are in sequence which is logarithmic and are in correspondence to the accuracy of the component. This enables the values present within the standard resistor category […]
Series 2S, 5S Li-Ion Cell Charger using BQ7718
This BQ7718 series 2S to 5S series Li-Ion cell charger is designed to monitor the voltage of each of the li-ion cells independently, with reference to an internally set reference level. As soon as any of the cell voltage tends to go above the reference level, it triggers an internal delay timer. This delay timer […]
