Intrinsic semiconduction is a property of a pure material. (True , False )

Engineering

True.

An intrinsic semiconductor is a pure semiconductor. At room temperature it behaves as an insulator because it only has a few free and hollow electrons due to thermal energy.

In an intrinsic semiconductor there are also electron fluxes and gaps, although the total current resulting is zero. This is because the action of thermal energy produces free electrons and gaps in pairs, so there are as many free electrons as there are gaps with which the total current is zero.

What is the difference between a Datum and a Datum Feature? a) A Datum and Datum Feature are synonymous. b) A Datum is theoretic
aliina [53]

Difference between Datum and Datum feature is<em> 'Datum is theoretical and Datum feature is real'. </em>

Option: (b)

<u>Explanation:</u>

A Datum is a perfect plane, line, point or surface but only occurs theoretically.

However a Datum Feature is fully based on a tangible surface, axis or point on a part where that theoretical datum is located.

The reason behind in this is they are not equal to each other because the 'part surface' is never 100% perfect.

The important functional features of the Datum is controlled during measurements.

The Double.parseDouble() method requires a String argument, but it fails if the String cannot be converted to a floating-point n
LuckyWell [14K]

Answer:

  1. import java.util.Scanner;
  2. public class TryToParseDouble {
  3.    public static void main(String[] args) {
  4.        Scanner input = new Scanner(System.in);
  5.        double num;
  6.        try{
  7.            System.out.print("Input a number: ");
  8.            num = Double.parseDouble(input.nextLine());
  9.        }catch(NumberFormatException e){
  10.            num = 0;
  11.            System.out.println("Invalid input! It should be a number in double type");
  12.        }
  13.        System.out.println(num);
  14.    }
  15. }

Explanation:

Firstly, create a Scanner object to get user input (Line 5).

Next, create a try block and prompt user to input a number and use Double.parseDouble() method to convert the input to double type in the block (Line 8-10).

Next, create a catch block to catch a NumberFormatException. In the Catch block, set the num to zero and then print out a message to inform user about the invalid input (Line 12-14).

Lastly, display the number (Line 16).

A single phase, 50-KVA, 2400-240-volt, 60 Hz distribution transformer has the following parameters: •
never [62]

Answer:

B) voltage at the sending end of the feeder = 2483.66 v

Explanation:

attached below is the the equivalent circuits and the remaining solution  for option A

B) voltage = 2400 v

   I  = \frac{50*10^3}{2400}  =  20.83 A

calculate voltage at sending end ( Vs )

Vs = 2400 +  20.83 ∠ -cos^-1 (0.8) ( 0.75*2 + 0.5 + j 2 + j2 )

hence Vs = 2483.66 ∠ 0.961

therefore voltage at the sending end = 2483.66 v
