A circuit is supplied with 30 VDC and contains three resistors connected in series. The value or R1 is 80 , the value of R2 is 1

,000 , and the value of R3 is 4,200 . What is the voltage drop across R2?

One approach to solving this is to first calculate the current the will flow through all three resistors:

The total resistance is R1+R2+R3 = 5280

I = V/R = 30/5280 ≈ 5,682 mA

Then the drop across R2 = I*R2 = 5,7mA * 1000 ≈ 5.682 V.

So this is based on the fact that V=I*R and there is one current running in the entire chain, ie., it is the same through each resistor.

Write a class named Averager containing: An instance variable named sum of type integer, initialized to 0. An instance variable
vladimir1956 [14]

Answer:

The answer to this question can be given as:

Class definition:  

public class Averager  //define class Average.

{

private int sum = 0;

 //define variable sum.

private int count = 0;

 //define variable count.  

public int getSum() //define function getSum().

{

return sum;  //return value.

}

public void add(int x)

//define function add().

{

sum = sum + x;   //calculate sum

count=count+1; //increase value of count.

}

public int add(int x)

 //define function add().

{

return count;  //return value.

}

public double getAverage()  //define function getAverage().

{

return (double)sum/count;  //return value

}

}

Explanation:

The above class definition can be described as:

  • In the above class definition first we define a class that is " Averager". In this class we define two integer variable  that is "sum and count"  and assign a value that is 0. Then we define a functions :
  • First we define getSum() function in this function we does not pass any value and the return type of this function is int that will return an integer value.
  • Then we define add() function we use this function two times but both functions have different from each other.  
  • In first time implementation, we define this function and the return type of this function is void which means it does not return any value. In this function, we calculate the sum value and increase the value of the count variable by 1.  
  • In second time implementation, we define this function and the return type of this function is int which means it will return a value. In this function, we will return the count variable value.
  • At the last, we define a getAverage() that calculates the average of the added values in the sum variable and returns its value.

Define a function that takes two arguments: a string called strText and a number called intNumber. This function will use a repe
natima [27]

Answer:

public class Main

{

   public static void printString(String strText, int intNumber) {

       for(int i=0; i<intNumber; i++){

           System.out.println(strText);

       }

   }

   

public static void main(String[] args) {

       

       printString("Brainly", 3);

}

}

Explanation:

- Define a function called <em>printString</em> that takes two parameters - a String and an int. Since the function will print out the given String, it's type will be <u>void</u>.

- Use <em>for loop</em> to iterate according to the given number and print the given string

- In the main, call the <em>printString </em>function with some parameters.

Choose the type of collection described.
Stella [2.4K]

Answer:

1) List

2) Dictionary

3) Tuple

Explanation:

A list uses square brackets. It is used to store multiple items in just one variable. They are usually changeable and give room for duplicates. You use append to add to the collection.

A dictionary uses curly brackets. You use update to add to the collection. A dictionary is created by placing the elements in curly brackets and separating them with a comma. It is changeable and it does not give room for duplicates.

A tuple uses parentheses. You cannot change it once you create it. It is an ordered list of elements that is finite and can also store multiple items in one variable.
