Answer:
Option a electronic switch used on FPDs
Explanation:
A thin film transistor (TFT) is an electronic switch which is commonly used in a liquid crystal display (LCD). TFT derives its name by the way how it is produced. It is produced by layering thin films of semiconductor. TFT is a type of transistor which is used to control state every individual pixel in a LCD. TCT can change the states of pixels (on and off) very quickly.
Answer:
Written in Python
for num in range(1,1001):
sum=0
for j in range(1,num+1):
if num%j==0:
sum = sum + j
if num == sum:
print(str(num)+" is a perfect number")
Explanation:
This line gets the range from 1 to 1000
for num in range(1,1001):
This line initializes sum to 0 for each number 1 to 1000
sum=0
This line gets the divisor for each number 1 to 1000
for j in range(1,num+1):
This following if condition line checks for divisor of each number
<em> if num%j==0:
</em>
<em> sum = sum + j
</em>
The following if condition checks for perfect number
if num == sum:
print(str(num)+" is a perfect number")
