Ullamot, Chillie B. BSEE 4-3 Activity 10 The video presented for activity 10 was all about circuit protection devices. The main purpose of the video was to look at or evaluate the fundamental circuit protection devices, including GFCIs, overloads, breakers, and fuses. It discuss their distinctions, modes of operation, and intended purpose in further detail. Devices that protect persons and property from electrical and fire risks are known as circuit protection devices. I learned that we are a circuit protection device since we have complete control over all the tools we employ. When it comes to circuit protection, the first line of defense against accidents and hazards is the concise act of not doing dumb things, as emphasized in the video. We must take extra precautions as electricity is just as risky as it is beneficial to us. Also, I learned that power is related to the square of current. A rise in current results in a corresponding rise in power. Similar to an emergency off switch, circuit protection devices fundamentally perform the same thing: they open up and halt the current flow. Technically, circuit protection devices are always connected in series to the electrical load they are meant to secure. The 15 amp fuse, which is less powerful than the 30 amp fuse in an automotive fuse, would essentially melt when the current exceeded it. Depending on how much care we take with it, electricity can either be an ally or a potential enemy. As long as we take every precaution to keep safety at the highest level, we should have fewer worries. We should also always have circuit protection devices to increase the safety features in our electric load and circuit. They all serve the same function, which is to safeguard our electrical equipment and circuits, despite the fact that these devices differ in their uses and intended applications.
