Even in this situation a freewheeling diode must be connected across a relay coil. Because the reverse back EMF from the relay coil may still have the potential to force enter the power supply or any associated circuitry and cause damage to the vulnerable electronic parts. How to Calculate rel...
This electronics video tutorial provides a basic introduction into the common emitter amplifier which uses a NPN bipolar junction transistor. This video explains how to calculate the voltage gain, current gain, and power gain of the CE amplifier circuit. Got Questions ! Your Answers> What is the ...
No calculus though, just ohm's law. Before we calculate anything though, let's set some variables. The meter is 100uA full scale deflection, and we'd like to make it 3mA. Looks like we'll need a resistor! Take a look at [image 2]. This is the scenario we must create. In ...
A LED indicator is also a useful thing to have. Add it to the output of the power supply, so when you power the speakers, LED will glow. Check thisinstructableto find out how to calculate the resistor value for your LED. Most pre-assembled amplifier boards have a potentiometer for volume...
If you have already wired up the driver as I have shown before, you can leave the Arduino connected to power the RST and SLP pins. Current limit formula The next step is to calculate the current limit with the following formula:
} // Calculate RMS value starting from the detected zero crossing double sumSquaredValues = 0.0; int startIndex = zeroCrossingDetected_index % 380; for (int k = 0; k < 384; k++) { int index = (startIndex + k) % 380; // Add the squared value to the...
choose a Zener diode with relatively smaller voltage variation. The one chosen for this example is the 2V variant in Figure 5. From its I-V curve, estimate the equation of the curve. This equation is used later to calculate the operating point of the Zener diode. Microsoft Excel...
TL431 is commonly used to create a voltage reference or small linear shunt regulator. It is often considered to be a “programmable Zener”. Though, there is a big difference betweenTL431 and a Zener diode. Like many other feedback systems, TL431 can oscillate if inappropriately decoupled. ...
The other secondary windings NSx are selected to be: Winding NS1 NS2 NS3 NS4 Turns 1.2 2.4 2.4 2.4 In this example the minimum number of turns is 5 on the primary winding and 6 turns on the first secondary winding. With NS1 selected, Equation 4 is used to calculate the maximum duty ...
