Question 1

Impedance

Answer 1

Hindrance to flow of current in AC circuits, its caused by capacitor and inductor which is part of AC circuits. In DC it is called as Resistance.

Question 2

Ohms Law

Answer 2

V=IR

Question 3

Electrical Power

Answer 3

P=I * V
P = V^2 / R
P = I^2 * R

Question 4

Internal Phase

Answer 4

Green Label: Engineering Final Cad Model
Blue Label: Validate Engineering
Red Label: Validate and Release

Question 5

COTS

Answer 5

Commercial-Off-The-Shelf,
Commercially available parts, there is no need to develop,
Connectors, Clips, Terminals Etc.,

Question 6

COTS procurement Suppliers

Answer 6

UL Certification (Underwriters Laboratories)
CE Certificaiton (Conformité Européene)
FCC Certification (US market)

All are certification process on product safety and quality.

Question 7

Netural vs Ground

Answer 7

Neutral: Part of normal operation in 3 phases, It will carry the current during operation for unbalanced current.

Ground: safety measure to provide least resistance path during fault current. not part of regular operations. This least resistance parth will give high sudden current flow which will trigger Circuit Breakers.

Question 8

FPGA

Answer 8

Field-Programmable Gate Array is a type of computer chip that you can program to perform specific tasks. Unlike regular chips that are made for one specific job, FPGAs can be changed to do different jobs after they are made. This means you can update or change what the chip does even after it has been installed. Think of an FPGA like a box of LEGO bricks. You can put the bricks together in different ways to create different structures. Similarly, you can arrange the components inside an FPGA to create different electronic circuits.

Question 9

Number of Strands

Answer 9

22 to 14: 19
12 to 10: 37
