A machine is a device that uses energy to perform a specific task or function.

• Machines can be powered by electricity, fuel, or human effort

• They can be simple or complex, ranging from a hammer to a computer

• Machines have specific parts that work together to achieve their purpose

• They can be designed for manufacturing, transportation, communication, and more

A CRO (Cathode Ray Oscilloscope) is an electronic device used to display and analyze waveforms and signals.

• The CRO works by using an electron beam that is deflected by electric and magnetic fields to create a visual representation of a signal.

• The front view of a CRO typically shows the screen, controls for adjusting the signal display, and input/output ports.

• To use a CRO, connect the signal source to the input port and adjust the controls to display the desired waveform.

• CROs ...read more

Array two sum problems and time complexities

• Two Sum: Given an array of integers, return indices of the two numbers such that they add up to a specific target.

• Time complexity: O(n)

• Space complexity: O(n)

• Two Sum II - Input array is sorted: Given an array of integers that is already sorted in ascending order, find two numbers such that they add up to a specific target number.

• Time complexity: O(n)

• Space complexity: O(1)

• Two Sum III - Data structure design: Design and implement a Two...read more

Single phase voltage is typically 120 or 240 volts, while three phase voltage is typically 208, 240, 480, or 600 volts.

• Single phase voltage is used in residential and small commercial applications.

• Three phase voltage is used in larger commercial and industrial applications.

• The voltage level depends on the specific application and electrical system.

• Examples of single phase voltage include household outlets and appliances.

• Examples of three phase voltage include large motors and...read more
