[QUOTE="welshwizard, post: 188, member: 3"] [B]Three Phase[/B] 1/. Can you think of any reasons why it is necessary to spread our loads across three phases rather than making things simple with one phase? [B]Electrical Cable[/B] 1/. Give three examples of good conductors: 2/. Give three examples of good insulators: 3/. Give an example of a material that is neither a good conductor or a good insulator: 4/. Knowing what makes a good conductor, what could we say about the numer of electrons in the outer shell of an insulator? [B]Exercise 3. [/B][B]Unit 2: Outcome 3: Session 3[/B] 1/. An engineering workshop is being wired in pvc/swa/pvc. Why? 2/. A three-bedroomed house is to be rewired. What cables would you choose and why? 3/. Why would you use aluminium cables rather than copper? 4/. Give three advantages of MI cable.
