Answer:
We will see a waveform displayed on the screen and it will be PWM(pulse width modulation) of sinusoidal wave,this wave should have a frequency of 14KHz and it will form a vibration spectrum.
Answer:
The efficiency of a DC generator is maximum when those losses proportional to the square of the load current are equal to the constant losses of the DC generator. This relation applies equally well to all rotating machines, regardless of the type of machine.
Explanation:
Answer:
208 mg/L
Explanation:
Only Mg++ and Ca++ causes hardness not Na+
Given
Mg++ = 20 mg/L
Ca++ = 50 mg/L
=
= 208.33 mg/L 208mg/L

Explanation:
Automation is a technology by which processes that are normally meant to be controlled by humans are electronically controlled. These can be through the use of robots, computer aided machines, etc.
For small scale industries, expensive automation should not be employed, it should rather be low cost, because of the financial abilities of these firms.
Low cost automation will improve the production of small scale industries in limited time. Humans cannot match up with machines that have been incorporated with programmable comptrollers in carrying out production processes. Such machines operate at a higher speed and Efficiency.
For example, In a small packaging company, microrobots can be made to serve this purpose while saving the continual cost of labour and at the same time ensuring efficiency.
A small mechanic workshop that decides to employ an automatic diagnostic tool will be more efficient and productive than the one that uses manual approach.
