RF designers think about 50 ohm, video designers 75 ohm, audio and telecommunication designers 600 ohm – there are many possibilities. All of these termination resistor values have a common purpose – ...

Ok, i have 8 3.6v (20mA) LEDs on a single 12v line with a 50 ohm resistor. My problem is that the amperage of all the LEDs exceeds 1W and my resistor is only a 1W. Could i make two sets of 50 ohm ...

The target he set himself was to measure the noise produced by a 50 Ohm resistor, which is the impedance most commonly seen on the inputs and outputs of RF systems. The formula for Johnson-Nyquist ...

Now, multiply 20 by 10,000 and you’ll get 200,000. This means that the resistor is rated at 200,000 ohms, more commonly expressed as 200 K ohms. Tolerance band Let’s take a look at the ...

50:50 square waves are, indeed, impossible. Figure 1 “Traditional two-resistor” 555 oscillator. However, fortunately, as illustrated in Figure 2, the classic two-resistor topology isn’t the only way ...

The 30 ohm resistor would increase this to 5,030 ohms. Individual variances in the piezos will dominate that. Adding in a piezo to our last calculation gives: 1/38 + 1/38 + 1/38 + 1/1000 gives 1/0 ...
