Wednesday 13 April.

Today i had my sixth class of comm, Health and safety and problem solving. Today we discussed health and safety issues concerning our business "hybrid solutions. Was a bit boring learning about the health and safety act 1992. We set up our company's health and safety policy's and also sketched the layout of our workshop. We didnt have to do our presentations as jonos laptop presentation program was to new for the unitec computer. I didn't mind not doing the presentation. All the work we have done is coming together now for our group portfolio.

Today i had my fifth class of comm, Health and safety and problem solving. Today i missed half the start of the class because traffic was really bad. I missed out on quite a few important bits of information which was a bit annoying. Today we discussed sustainability which includes a social, Environmental, Economic and Governance aspects. We related these aspects to our project. Our group finalized our name and logo. The name is hybrid solutions and the logo is a green car. We then presented those aspects that relate to our project to the rest of the class. We presented with a power point made at the last minute apart from that the rest of the presentation went smoothly.

Today i had my fourth class of comm, Health and safety and problem solving. I found out the firsts assignment due date. Which means i will have to get motivated. We discussed what our group project/portfolio was going to be about.Our project is on hybrid vehicles. The discussion went well. We had another member join our group. This made the workload a little bit easier. Then we had a library introduction course. That went alright was a bit boring as I already knew most of what was told. Next was the referencing course which was good because i learned how to properly reference. Now I can start assignments from all my classes.

Today i had my third class of COMM, Health and safety and problem solving. Today we discussed communication, the importance of customer service and problems business can face with employees and customers.I learned a few new things about the meaning of communication and problems many people face. We then presented our findings with the rest of the group. That went average as i don't think we were adequately prepared. For the next time will have to write more notes/key points on our papers. To achieve a better presentation. Should get better with more practice.

Today i had my second class of COMM, Health and safety and problem solving. I learned what is required to pass this class. Half the marks are for a group presentation and a group portfolio. The other 40% is from two written assignments on various topics. The last %10 is for completing this blog every week after class. These requirements should be fairly easy.I started my group portfolio today on the topic what is the biggest problem in your industry. In my group is Haroon, Jono, Kevin and myself. We disused alot of problems for the automotive industry including lack of fuels, emission and safety problems and alternate fuels and energy's to run a car. My group works well together we generally agreed on what topics were do-able and which ones weren't. It was a good start for our group. We should work well for future group activity's.

Coil primary
1= 0.7 Ohm
2=0.8 Ohms
3=0.6 Ohms

Coil secondary
1=12.2K ohms
2=12.3K ohms
3=12.3K ohms

Testing Ballast resistors
Part no: BR1
Resistance= 1.2 Ohms.

Standard Single tower coil




1. Wire up a ballast resistor in series with your coil primary winding values as shown in
the following diagram.
2. Connect an ammeter in series and note the current draw.
3. Measure and note the voltage drop across the ballast resistor.
4. Measure and note the voltage drop across the coil primary.

Current draw was 3.1A
Coil calculated voltage drop=6.51V
Coil measured voltage drop=10.6V
Ballast resistor calculated voltage drop=3.72
Ballast resistor measured voltage drop=1.3V
