This week we furthered our knowledge in the area of circuits. We already knew about the two basic types of circuits which were series and parallel. Series are when the resistors are in a row next to each other or one path of current. Parallels are when the resistors are spread out on different currents or multiple paths. This week we learned about combo circuits, which consist of both series and parallel resistors. I used the picture of a microwave because a microwave is an example of an object that uses combo circuits. It uses combo circuits because of the way it powers itself to heat up your food. In physics to solve a combo circuit you need to follow four steps. The first step is the find the REQ or total resistance in the circuit. The next step is to find the I-Batt which is the total voltage divided by the REQ. The third step is the find the voltage drop across each resistor. Then finally the last step is to find the current through each resistor. Parallels have the same voltages but when finding the resistors you must first add them in inverse. But for series they share voltages and split the resistance.
