When replacing a defective switch, what is a necessary characteristic of the new switch?
Select one:
a. Greater number of poles and throws than the original switch
b. The same number of positions as the original switch
C. Identical cover plate as the original switch
d. Greater current ratings than the original switch
So, according to it the correct answer is option d. Greater current ratings than the original switch.
What is a switch?
A switch is a component of physical circuitry that controls the flow of signals. A switch or toggle switch enables the opening or closing of a connection. The switch permits a signal or power to pass through the connection when it is opened. The switch cuts the circuit connection and halts the flow when it is closed.

Numerous engineering and scientific applications require finding solutions to a set of equations. Ex: 8x + 7y = 38 and 3x - 5y = -1 have a solution x = 3, y = 2. Given integer coefficients of two linear equations with variables x and y, use brute force to find an integer solution for x and y in the range -10 to 10.
Ex: If the input is:
8
7
38
3
-5
-1
Then the output is:
x = 3 , y = 2
Use this brute force approach:
For every value of x from -10 to 10
For every value of y from -10 to 10
Check if the current x and y satisfy both equations. If so, output the solution, and finish.
Ex: If no solution is found, output:
There is no solution
Assume the two input equations have no more than one solution.
Note: Elegant mathematical techniques exist to solve such linear equations. However, for other kinds of equations or situations, brute force can be handy.
The brute strength method determines if each x and y value satisfies both conditions. To do this, we must iterate through each result in the specified range and insert them into both models.
What are Elegant mathematical technique?ALGORITHM :
1. Take the values of all coefficients and SET flag = FALSE
2. Run a FOR loop for x in range (-10, 11). 11 won't be included.
2a. Inside the first FOR, start the y FOR loop in range(-10,11). 11 won't be included
2b. Inside the y FOR loop, check IF for a particular value of x and y both the equations satisfied.
2c. If yes, set flag TRUE and print values of x and y.
2d. ELSE the flag stays FALSE.
END FOR Y
END FOR X
3. Check if flag = FALSE, then print NO SOLUTION
PYTHON CODE :
a=int(input()) #taking input for each coefficient
b=int(input())
c= int(input())
a1= int(input())
b1= int(input())
c1= int(input())
flag = False
for x in range(-10,11): #checking for all values of x in range -10 to 10
for y in range(-10,11): #checking for all values of x in range -10 to 10
if (a x + b y – c == 0) and (a1*x + b1*y - c1 == 0) : #checking if the x and y values satisfy the equation
flag = True #setting the flag if solution is found
print('Solution : x = {-10, 10}, y = {-10, 10}'.format(x,y)) #if they satisfy print x & y
if flag = False : #if flag stays false, that means there is no solution
print('No solution')
OUTPUT : The output is given below.

15. How many PC’s can be connected to a UPS?
Answer: Depends on the power of the computer /computers and the UPS
Explanation: For someone who had a big connected network of computers and printers we would plug the computer or server into the UPS as well as the monitor and sometimes a printer sometimes the monitor was plugged into the wall
When you get a UPS you must plug it in for a certain time could be hours or even a day. A USP has a big battery in it and you must charge it (sometimes it comes semi-charged but you must plug it in to strengthen it. )
there are two connector wires that you affix to the battery and you must put a lot of strength into it to make it secure.
So in closing, you can get away with two like a desktop and a laptop.

A square QR code contains 40×40 tiny squares (pixels) where each tiny square represents a 0 or a 1. Calculate how many bytes of data can be stored on the QR code
Answer:
Explanation:
QR Codes are made of multiple rows and columns. The combination of these rows and columns makes a grid of modules (squares). There can be a maximum of 177 rows and 177 columns which means the maximum possible number of modules is 31,329. With the eye, these are just small squares and mean very little, but the exact arrangement of those modules allows the QR Code to encode its data. This means that, unlike traditional barcodes which are 1 dimensional and use 1 row of lines, QR Codes use 2 dimensions which allows them to store a lot more data in the same area of space.

What is a worksheet?A worksheet is a sheet that is used as a guide in doing some work to make preliminary plans, supplementary computations, notes, or comments.
Charts are used to display a series of numeric data in a graphical format in order to help people understand large amounts of data and their relationships.
Good graphs allow for precise estimation of the quantities represented. The reader must understand the scale used to represent quantity on the graph in order to estimate quantities.
Create your graph with as few elements as possible. Color can help distinguish data sets in a graph, but avoid glaring color combinations (such as chartreuse and violet), as these can be distracting.
Vertical bars are used to describe information in column charts. They can work with a wide range of data, but they are most commonly used for information comparison. Line charts are excellent for displaying trends.
Thus, by using some things like this, one can make charts clearer.
