single BJTs become sufficient for getting moderate output current, however when higher output current is required, it becomes necessary to add more number of these devices together. Therefore it becomes necessary to connect theses devices in parallel. Thoughusing single BJTsis relatively easier,...
A good way to counter this is to connect many smaller rated diodes in parallel, however since diodes just like BJTs are semiconductor devices, don't go well when connected in parallel. The reason being, each diode connected in the parallel string could have a slightly different switch ON leve...
I mounted my amp in the front trunk, which gives short cable runs to the speakers, head unit, and battery. It's also a less obvious location for thieves to look. The downside is the potential for noise from the various electronics mounted up there, particularly the power steering. ...
Batteries, whether they're those cylindrical, alkaline AA's or rechargeable lithium-polymers, usually look like a pair of disproportionate, parallel lines: More pairs of lines usually indicates more series cells in the battery. Also, the longer line is usually used to represent the positive termin...
One detail on the spec sheet that you want to be sure to check is the ohms rating. Ohms are a unit of measure for the impedance or resistance in a piece of gear.To understand impedance, imagine a hose plugged up with gunk slowing the water flow. If you want more water to come out...
Hence, my battery can theoretically discharge the current as high as 4.2V/0.24=17.5A (short circuit maximum current at fully charged state) but it is not good to do so. If higher current output is desired, more batteries should be connected in parallel to reduce the overall internal resistan...

Potentiometers: 10K Ohms, but can be substituted with 1K to 3K Ohm resistors In the diagram above, the blue wire connects to the Raspberry Pi’s SDA pin. The yellow wire connects to the Pi’s SCL pin. Enable I2C on the Pi Before we get into the programming, we need to make sure ...
There are many ways to configure LiFePO4 Cells in series or in parallel/series. When possible, I tend to prefer the simplicity of a 4S configuration, if that cell size works for the desired Ah capacity. 4S requires less overall connections and less work when doing cell balancing. Some would...
In particular, on some instruments, leaving the function selector set at Ohms ( Ω ) and then touching the probes to live AC or DC current may damage the instrument and may be unsafe.At above-left we illustrate the proper function setting when using the Extech 430 DMM to measure voltage....
