Ch+18+-+DC+Circuits

There are two ways to connect the components in a circuit: series and/or parallel. In a series circuit it is important to note that the current for every component is of the same value, however there is a different voltage drop for each component. Also, if there are resistors connected in series, then inoder to find the equivalent resistivity, the resistors can be added together, as seen below: R(eq) = R1 + R2 + R3 + ....ect media type="file" key="wiki series" However, parallel circuits are the complete opposite. In parallel, the voltage is a constant, and the current varies for each component. Then if there are several resistors set up in parallel, then to find the equivalent resistivity, there must be 1 over the resistor values and then they can added, once that value has been found, a 1 must be placed over that value too, as seen below: 1/R(eq) = 1/R1 + 1/R2 + 1/R3 + ....ect media type="file" key="wiki parrallel"
