Do not add the DLE and ILE together to calculate the maximum error that may occur at any digital step. The maximum error values specified in the device datasheet are the worst error values measured in a laboratory test environment over the given voltage and temperature range (refer to...
How to Calculate Capacitance of a Capacitor?It should be obvious from the physical construction of capacitors that connecting two together in parallel results in a bigger capacitance value. A parallel connection results in bigger capacitor plate area, which means they can hold more charge for the ...
It will be great if you are able to read its color code. However, color code might not be available. The best thing is to design a simple circuit that has both resistors properly arranged in series and determine the voltage over the resistor. After this, you can just input all these v...
A simple circuit to demonstrate how to calculate your power rating. In the circuit above, we have a LED that has a 2V voltage, a resistor with a 350 Ohm value, and a power supply giving us 9V. So how much power will dissipate in this resistor? Let’s add it up. We first need t...
SMD Soldering Practice Kit, or How I Learned to Stop Worrying and Love the Cheap Chinese Kit: This is not an Instructable about soldering. This is an Instructable about how to build a cheap Chinese kit. The adage is that you get what you pay for, and he
Reflow Soldering usesSMT (Surface Mount Technology)to solder SMD (Surface Mount Devices) on to the PCB. In Reflow soldering there are four stages – Preheat Thermal soak Reflow; and Cooling. In this process solder paste is printed on the track of the circuit board where the component is to...
value. The Arduino will measure the voltage at the capacitor and record the time it takes to reach 63.2% of it’s voltage when fully charged (the time constant). Since the resistance value is already known, we can use the formula above in a program that will calculate the unknown ...
It is important to note that the measured value of a resistor placed in a circuit may be different due to effective resistance resulting from series or parallel combinations. With a clamp meter, you can also measure the resistance value of any SMD resistor, any electrical path, or even wire...
To help limit the bias current of the feedback resistor divider, RFBT is selected to be 49.9kΩ. Equation 18 is used to calculate the value of RFBB. RFBB = RFBT VLOAD VREF − 1 = 49.9kΩ 12V 1V − 1 = 4.54kΩ (18) RFBB is selected to be 4.53kΩ 2.11 Control Loop ...
