Explanation / Answer
Example for troubleshooting electronics or electrical devices.
The 5 Step Troubleshooting Approach consists of the following:
Preparation
Step 1 Observation
Step 2 Define Problem Area
Step 3 Identify Possible Causes
Step 4 Determine Most Probable Cause
Step 5 Test and Repair
Follow-up
Troubleshooting motor drives. Because most failures occur within the power sections instead of the circuit boards, they aren't very difficult to troubleshoot. The typical plant maintenance technician will rarely see enough failures to build up any proficiency in repairing circuit boards.
1. First isolate the box or section that isn't passing the signal and then work on it. Make sure that the capacitors are discharged before putting your hands into the power section. With the power off, begin checking the power sections of the drive. Then, place your digital multimeter (DMM) in the diode check mode
Find the positive DC bus (sometimes this may be brought out to a terminal), place the negative (black) lead from your DMM on it, and then check each incoming phase in turn with the positive (red) lead. You should read a diode drop of about 0.6V on each phase. If it reads open, then the charge resistor is open and needs to be replaced. This is a common source of many problems.
2. Next, place the DMM's positive lead on the negative bus and the negative lead on each incoming phase in turn as you did before. You should read a diode drop, not a short or an open. Place one DMM input lead on the positive bus and the other on the negative bus. On this measurement you should read the capacitor charging rather than a short.
3. To check the inverter section, place the positive DMM lead on the negative bus and the negative lead on each output phase. You should read a diode drop because diodes are connected across each output transistor. Again, you shouldn't read a short. Check the remainder of the inverter section by placing the negative lead of the DMM on the positive bus, checking each output phase again with the positive lead of the DMM. You should read a diode drop again and not a short. If you read OPEN from either of these checks then the bus fuse is most likely open. If no problems are present within the power section and the unit still won't function, it's either improperly connected or programmed or has a bad circuit board.
Newer PWM drives use IGBTs in the driver sections of the output, and are much less likely to fail. These devices perform like a metal-oxide semiconductor field effect transistor (MOSFET). When the voltage at the gate exceeds the threshold voltage, the device turns on. If the voltage applied to the gate contact is less than the threshold voltage Vth, then the device is turned off
#2: Do you see yourself working more hands on with hardware or are you more interested in the programming and software levels of technology?
I am more interested in the programming and software levels of technology, software development involves development of software following software development rules and it also involves analysis of algorithm.
Example includes video games, operating systems and software’s.

Modern technology has revolutionized people’s communication. Radio, telephone, satellite communication, cellular technology, wireless Internet … in the modern day two people can chat with a help of computer when they're in different places. Technology is building bridges between people on opposite sides of the globe, bringing people from all cultures and backgrounds into contact with each other.
The Internet hosts an enormous information base. Technology has made it possible for this information to reach far and wide. Online education has set in, making it possible to render knowledge to students inhabiting remote locations on Earth. It is due to the World Wide Web that the information could reach one and all over the computer networks.
Technology is not only about technology itself or more efficiency and discovering new methods and processes; we have to add the component of art which is about to make wise choices for the future of technology.
The rise of cloud computing, cloud storage, Artificial intelligence and Machine learning is the example, that we will be soon on the node that connects our body and capture the data of human activities in real time
Technology has a positive and negative impact on our daily life. Today we live more appearance filled the life. The craze and disadvantages of taking selfies in the risky area are well known. We do online shopping and there are varieties and price comparison tools.
Today, we do same things on social media but without emotions. This is the technological effect. And we’re responsible for this change. It’s is good or bad, depends on the users, how they’re using it.
