A single line diagram for HT to LT panel diagram is a simplified representation of the electrical system.
The diagram shows the flow of electricity from the high voltage side to the low voltage side.
It includes all the major components such as transformers, switchgear, and distribution panels.
The diagram also shows the protective devices such as fuses and circuit breakers.
The single line diagram is used for planning, de...
DOL starter is a type of motor starter that directly connects the motor to the power supply.
DOL stands for Direct-On-Line
It is the simplest and most common type of motor starter
It is used for small motors with low starting current
It provides full voltage to the motor during starting
It does not provide any protection against overloading or short circuits
Load calculation can be done by measuring the power consumed by the load and dividing it by the voltage supplied.
Measure the power consumed by the load using a wattmeter
Divide the power by the voltage supplied to get the load in amperes
Use the formula P=VI to calculate the power consumed by the load
Consider the power factor of the load while calculating the load

The task is to encode and decode 'SECRET_INFORMATION' for security purposes and determine if the transmission was successful.
Read the number of test cases 'T'
For each test case, encode the 'SECRET_INFORMATION' and then decode it
Compare the decoded string with the original 'SECRET_INFORMATION'
Print 'Transmission successful' if they match, else print 'Transmission failed'

Given an array Arr
consisting of N integers, your task is to find the equilibrium index of the array.
An index is considered as an equilibrium index if the sum of elem...
Find the equilibrium index of an array where sum of elements on left equals sum on right.
Iterate through the array and calculate prefix sum and suffix sum at each index.
Compare prefix sum and suffix sum to find equilibrium index.
Return the left-most equilibrium index or -1 if none found.
