What is transformer and its function?

Computers and Technology
1 answer:
Anna007 [38]3 years ago
4 0

Answer:

A transformer is an electrical device which, by the principles of electromagnetic induction, transfers electrical energy from one electric circuit to another, without changing the frequency. The energy transfer usually takes place with a change of voltage and current.

The major function of a transformer is to step up or step down the voltage in an Alternate Current (AC) circuit.

Write a Python 3 program to read from a .csv file containing rates from power companies. Your program should determine the avera
aliya0001 [1]

Answer:

In python:

file = open("rates.csv", "r")

ratecount = 0

ratesum = 0

mylist = []

rates = file.readlines()

for nums in rates:

     num = nums.rstrip('\n')

     mylist.append(int(num))

     for i in num:

           ratesum= ratesum + int(i)

           ratecount = ratecount + 1

print("Maximum Rate: "+str(max(mylist)))

print("Minimum Rate: "+str(min(mylist)))

print("Average Rate: "+str(ratesum/ratecount))

Explanation:

This opens the csv file

file = open("rates.csv", "r")

This initializes the number of rates in the file

ratecount = 0

This initializes the sum of the rates

ratesum = 0

This initializes an empty list

mylist = []

This reads the rates into lines

rates = file.readlines()

This iterates through the rates (as a string)

for nums in rates:

This removes the newline character \n in the rates

     num = nums.rstrip('\n')

This appends the rates (as an integer) to the empty list

     mylist.append(int(num))

The following counts the rates in the file and also sum them up

<em>      for i in num: </em>

<em>            ratesum= ratesum + int(i) </em>

<em>            ratecount = ratecount + 1 </em>

This prints the maximum of the rates

print("Maximum Rate: "+str(max(mylist)))

This prints the minimum of the rates

print("Minimum Rate: "+str(min(mylist)))

This calculates and prints the average rate

print("Average Rate: "+str(ratesum/ratecount))

How many bits are necessary for a binary representation (unsigned) of:
pshichka [43]

Answer:

Hi!

The answer to:

a. 6 bits.

b. 9 bits.

c. 26 bits.

Explanation:

a. For the states of the U.S.A, you need 50 or more combinations to represents each element.

<u>If you use 6 bits, the possible combinations are 2⁶ = 64.  </u>

b. For days in a year, you need 365 or more combinations to represents each element.

<u>If you use 9 bits, the possible combinations are 2⁹ = 512. </u>

c. For inhabitants of California, you need 36,457,549 or more combinations to represents each element.

<u>If you use 26 bits, the possible combinations are 2²⁶ = 67,108,864.</u> If you use 25 bits instead of 26, then you have 2²⁵ = 33,554,432 combinations. These possible combinations are not enough to represent each inhabitant.
