Sometimes, you can also determine both from the size of the pins which are different for both terminals. However, this is not always true since manual cutting and human errors can sometimes make them alike and it gets difficult to differentiate between anode and cathode. Don’t worry, you ca...
Before selecting a suitable DC-DC adjustable step-down module, it is crucial to determine the electrical requirements of the high-power LED you intend to drive. This information is typically provided in the LED’s datasheet and includes the following parameters: Forward Voltage (Vf): This is t...
When a series LED connection is in question, you will just need to replace the "LED forward voltage" with "total forward voltage" in the formula, by multiplying FV of each LED by the total number of LEDs in the series. Suppose there are 3 LEDs in series then this value becomes 3 x ...
Determine the base bias voltages by measuring the voltage difference between the two ends of the base resistor (Rb). This should be equal to the supply voltage (Vcc). Determine the voltage drop between the collector and emitter junctions (Vce) of the transistor using the formula Vce = Vcc -...
The PG-2R voltage regulator and power conditioner from Black Lion Audio. “We see the audio industry as constantly improving when it comes to things like interfaces, preamps, and monitors,” Berman says. “But there are certain parts that kind of got left behind, where you see the same ...
LEDfwdV = 3.3V x 3 = 9.9V since 3nos are there in each series and 3.3V being the forward voltage spec of each LED LED current = 350mA, let's take it 300mA or 0.3Amp to keep things cooler. Substituting these in the formula: ...
The following calculations can be used to determine a suitable burden resistor for CT. Here, we did not consider the impedance of secondary windings of CT. By considering impedance of Secondary winding, we will get more accurate value of burden resistor. ...

PROBLEM TO BE SOLVED: To suppress a phase current generated in winding of a stator over a full speed range of motor when driving a stepper motor in a voltage mode.バガレリ フルビオ ギアコモマラノ ビンセンツォポリ エンリコ
Imagine an electric train with a motor like this: it would keep shuffling back and forward on the spot without ever actually going anywhere. Sponsored links How an electric motor works—in practice There are two ways to overcome this problem. One is to use a kind of electric current that ...
