Fetch the last traded price (LTP) as well as Price Change (%) for NIFTY 50 (50 stocks) and Bank NIFTY (12 banking stocks) in Excel sheet.   With this the fetched data can be analyzed to predict the price movements of both NIFTY 50 as well Bank NIFTY in Excel.   With the Refresh Button the price data can be updated.   Since the Excel files are VBA Macro based, enable the contents, and allow to fetch the data. ERRORS These works are in beta stage, so there are many unexpected errors. Due to the lag to fetch the data from the NSE server, Run-Time Error can occurs. See the screenshot. Save and close the Excel. Open after some time and Refresh. If it takes long time to fetch the data, close. Open after some time and Refresh.

          Assume charging a completely discharged capacitor, under resistance, R with an applied potential, E having the capacitance, C. Potential across the capacitor is E c . At time, t = 0s or t o :   E C < E; E C = 0 V. If it is fully charged then E C = E and t = t c . ‘E’ is the maximum potential attained by the capacitor. Time to reach maximum potential is: (t c – t o ).   At any given time, ‘t’ on charging in between t o and t c the potential of the capacitor, E C is related to the maximum potential, E by the relation, where ‘t’ is the elapsed time during charging ‘R’ is the resistance in Ω ‘C’ is the capacitance in F.   The product of R and C is called the time constant and is represented as, τ. So, τ = R × C.   Unit for τ τ = R × C = Ω × {F} = Ω × {C × V –1 } C = Charge in Coulombs = A × s = Ω × {A × s × V –1 } = = Ω × {V × Ω –1 × s × V –1 } = s. At one time constant, capacitor is 63.2% charged. I

Full width at half maximum (FWHM) for a curve is used in many scientific experimental data analyses. For instance, in X–ray diffraction analysis of crystal data, it is used to find the grain size from the curve. FWHM is the width of the curve or simply the difference in the corresponding two ‘x’ data values at y max /2. y max refers the highest value of ‘y’ or ‘y’ value for the maximum peak height.   Example Set of ‘x’ and ‘y’ data and the corresponding curve is given below: (View this Page for back reference.)     x      y 0.0    0.000 0.1    0.146 0.2    0.284 0.3    0.414 0.4    0.536 0.5    0.650 0.6    0.756 0.7    0.854 0.8    0.944 0.9    1.026 1.0    1.100 1.1    1.166 1.2    1.224 1.3    1.274 1.4    1.316 1.5    1.350 1.6    1.376 1.7    1.394 1.8    1.404 1.9    1.406 2.0    1.400 2.1    1.386 2.2    1.364 2.3    1.334 2.4    1.296 2.5    1.250 2.6    1.196 2.7    1.134 2.8    1.064 2.9

  Formula   C s - Specific capacitance (F/g) = to be calculated. A - Area under the I vs. E curve (AV) = 0.0154 m - Mass of the electrode material (g) = 20 mg = 0.02 g ν - Scan rate (V/s) = 10 mV/s = 0.01 V/s dV - Potential window (difference in potential) = 0.3 (= 0.0 V (-0.3 V))   Area (A) under the curve can be calculated using Origin program , whereas 'dV' is the difference in the potential.

Blue Fishes There are 200 fishes in a pond. 99% fishes are blue. How many blue fishes should be removed to make the percentage of blue fishes in to 98%? Hint: 2 is not the answer. Answer First, why '2' is not the right answer? If you think 198 is the initial number of blue fishes and if 2 blue fishes are removed, then there will be 196 blue fishes and hence in terms of percentage it is 98. But its wrong, since the total fishes count also decreased to 198, if you just remove 2 blue fishes alone. So the percentage of blue fishes are (196/198) × 100 = 98.99% Its not 98% its almost 99%. In simple, 198 blue fishes and 2 other colored fishes are there initially. And if you remove 100 blue fishes, then 98 blue fishes with 2 other colored fishes. So, the percentage of blue fishes becomes 98. Answer: 100 blue fishes should be removed. Show the Answer Tennis Match Antony and Benjamin played tennis against each other. Its a bet game and

Arduino – LCD I2C 16x2 display - Tinkercad Simulation LCD displays with I2C LCD adapter are 16×2 and 20×4 character LCD displays. This I2C LCD display contains 4 pins: Ground, VCC, SDA, and SCL. Arduino Code at Tinkercad:  https://www.tinkercad.com/things/68gKMm2VFm6 Circuit First, check the address of the I2C LCD with the following code: #include <Wire.h> void setup() {   Serial.begin(9600);   Serial.println("\nI2C Scanner");   Serial.println("Scanning...");   byte device_count = 0;   Wire.begin();   for (byte address = 1;         address < 127; address++ ) {     Wire.beginTransmission(address);     if (Wire.endTransmission() == 0) {      // Serial.print ("Found address: ");       Serial.print("I2C device found at address 0x");       Serial.print(address, HEX);       Serial.println("  !");       device_count++;       delay(1);     }   }   Serial.println ("Done.");   Serial.print ("Found ");   Serial.print (
