Electronics

I choose the topic because it is a hobby of mine. The process of creating a small circuit is very interesting to me. It seems simple at first but there is certain mathematical laws, such as Ohm’s law, which must be taken into consideration. Diagrams exist to help demonstrate a circuit. There is two type of currents that power a circuit. First there is an alternating current which changes direction back and forth. Secondly, there is a direct current, which only travels in one direction. There is also three important factors that must be taken into consideration before building a circuit. One of those factors is voltage, which is how much power is being supply. Another factor is current, how much electricity is traveling through the circuit, this is usually measured in amps. Lastly, resistance is needed, resistance is how much voltage is dropped throughout the circuit. There are various machine, such as a multimeter which can help you figure out these variables. Other important things to remember are basic things such as, making sure positive is connected to positive and negative to negative.
