Electrical Engineering information
would like to demonstrate a few more experiments here to give you
better understanding about physics which going on inside lamps.
Here we will talk about powering those light bulbs with dc "ballasts" or better say DC power supplies or converters.
The purpose of this
article is to help audio enthusiasts, who decided to buy bluetooth
audio amplifier board XH-M314 TPA3118 2x45W from China. It was not
designed properly and as it seems I found the fix.
In the new era of LED (Light Emitting Diodes), most of consumers start
forgetting CFL (Compact Fluorescent Lamp) & CCFL (Cold Cathode
Fluorescent Lamp). ...apparently fluorescent tubes received second life.
Over and over again I see the very loose usage of terminologies.
This may help us to understand each other.
This calculator helps to compute current limiting capacitor for low frequency (below 60Hz) AC sources of voltage.
This is a simplified battery capacity calculator to estimate the needed
battery capacity if you have known load currents. You need to know: a.
Time needed to run your loads in hours b. Load currents in A.
This is a simplified run-time calculator to estimate the run-time of your loads for Li batteries. You need to know: a. Battery capacity in mAh (mili Amp hours) b. Load currents in mA.
note 1Ah=1000mAh and 1A=1000mA. So if you have large car battery with
20Ah capacity, then put 20000 (mAh) as a number.
This page will give you some basic knowledge about wires and also provide and few useful calculators for different electrical parameters, dependent on wire size.
Please note: WE DO NOT SELL WIRES.
