Observations

  Technology has been around since the beginning of humanity's ability to think and innovate. Nowadays, the technology we have is capable of doing monumental things. Our lives, schooling, and work are dependent on it at this point. We use our technology as a means to an end; a way to make things easier, faster, and convenient. Some things we treat more as tools or everyday interactions, such as street lights, kitchen appliances, and cars. They exist, and our lives are drastically inconvenienced or made worse in their absence. Some pieces of technology are treated with more care and conscious appreciation, such as our phones or expensive cameras and game systems.
   People interacting with other people is more rooted in language and fluctuating emotions, but there are a few similarities. People we hold in higher regard are treated with more care than just the average stranger or acquaintance. Our personalities and mannerisms change depending on who we talk to. We're more conscious of ourselves when dealing with other humans.
  With the environment, people have learned to accept certain things as fact; it gets dark at a certain time of the day, the sun can hurt you, rain falls from the sky, etc. At this point in time, we seem to treat our environment as an obstacle to be overcome. Rain inconveniences us. Too much sun will burn. Those trees are in the way of our construction plan. This storm will cause a lot of damage. We accept everything because our environment has more power over us. We can't control the laws of nature, so we have learned to live alongside it as best we can.

1. Electrons move much slower through a current than the actual electrical motion that is transmitted between them, which is equivalent to the speed of light.  
2. Resistance refers to when electrical current is reduced through an object (called a load) or a process that limits the amount of flowing energy. Through this, electrical current can be converted into an output. Light bulbs are resistors that produce light waves, and indoor heating systems convert electrical energy into a steady source of heat. Resistors don't always have to produce an output of some kind; they are frequently used to limit the current so as to prevent overheating, damage, etc.
3. With direct current, the size and direction of the current is always consistent. This can be seen with batteries, whose potential energy and output is constant regardless of circumstances. Alternating current is current whose direction and size changes cyclically, often 50 or 60 times per second. Outlets in your home work using alternating current.
