For our project we decided to disassemble and understand a Memphis 1 Channel Mono Block Amplifier. First we started by disassembling the amp down to the main circuit board. From there we assigned ourselves different components to understand what they were and how they worked inside the amp. We all researched our components and got back together to discuss and figure out the flow of power and operations of the amp worked. A general idea of what the amp does is as follows. Power comes into the inputs

interior breaker issue. I also know that the power company has no reported outages in the area. I do know that the house was built in the 50’s and the electrical panel has not been upgraded since the home was built. Based on this information my hypothesis is that issue is within the main breaker outside the home. Due to the age of the home and electrical panel, it is likely a burnt out fuse that has caused all the lights to not work. Just to be sure I have tested the interior breakers of the house

energy, including but not limited to the following: A manually operated electrical circuit breaker; a disconnect switch; a manually operated switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors, and, in addition, no pole can be operated independently; a line valve; a block; and any similar device used to block or isolate energy. Push buttons, selector switches and other control circuit type devices are not energy isolating devices. Lockout. The placement

3.GENERATION Third electronic generation was between 1964 to 1971. Innovations in this era include the use of integrated circuits, or ICs which were invented by Jack Kilby and Robert Noyce . ICs are semiconductor devices with several transistors built into one physical component. Computers were able to run different applications at same time with a program that control the memory. There were invented a lot of techniques to improve proccesing. For example multiprocessing - execution of multiple

maintenance. This smaller more reliable transistor replaced the older vacuum tube. (Bellis) Transistors are semi-conductor devices that are used to amplify and switch electronic signals and electrical power. Transistors are composed of a semiconductor material with at least three terminals for connection to an external circuit. Transistors are manufactured in different designs but all have at least the three leads, the base which is responsible for activating the transistor, a collector which is applied to

I made sure to check that the correct cables had been selected for the task they were put in for. I also made sure that they were the appropriate size and that the size of breaker was also correct c) I checked that the correct circuit breakers had been fitted for the circuit they were to protect and that they were in the correct order as stated on the test sheet. Also that they were connected properly and tightened down. I also checked this on the RCD’s that were

Renee Montaque 1.2 M2 Why copper is used in electrical cables Mobiles have lots of different metals in them for example, Copper is used for electrical circuits and they are good conductors. Silver is used for switches on a circuit board and phone buttons because it's a really great conductor. Gold is used for the surface of the circuit board and a connector. Tantalum is used in electronic components and it allows scientists to make small mobiles and phones have palladium, aluminium and
