Slide 1Slide 2Slide 3Slide 4Slide 5Slide 6Slide 7Slide 8To make sure buildings have the right type of power.Through an electrical distribution grid. There are a few voltage differences throughout. Some of these voltages are too high, so they are decreased by transformers. There are different voltages required for different building types.For bigger buildings, such as museums, there are fuel-powered generators that will provide electricity until the grid is fixed. The main drawback to this is that it takes about 15 minutes to warm up and actually start.For this problem, there are Uninterrupted Power Source (UPS) systems, which is essentially a battery.The workers find out where the problem is and work their hardest to fix whatever the problem is.Electrical Generators use AC (alternating currents from spinning magnets)Batteries use DC (direct current)Adapters and converters are used to change the voltages of these and to switch from AC to DC in certain instances.Series Circuit: resistors are arranged one right after the other in a chain. (like Christmas lights)Rtotal = R1 + R2 + …Parallel Circuit: the current branches on the way to each resistor, and comes back together after it passes through each resistor.1/RT = 1/R1 + 1/R2 + …If one part of the series goes out, the flow of electricity will be cut off from the rest of the series.Also, in parallel, each part of the circuit can be individually turned on or off without affecting the rest of the circuit.•Don’t become a part of the circuit or you’ll cause a short circuit (lower-resistance connection interrupting the flow). A circuit breaker (opens the circuit when current is quickly increasing) will not always save you.•Be grounded. A grounding wire can connect to metal and to the earth to ground you.•Turn off the power before working on
