Series Circuits
We learn about the properties of series circuits. We examine how to find the total voltage, current, and resistance of a series circuit and learn how to find these things across individual resistors within the circuit.

Vocabulary
closed circuit - a circuit with no breaks, in which current can flow continuously. equivalent resistance (Req) - the total resistance of a collection of resistors; for a series circuit, is equal to the sum of the resistances of the individual resistors. For a parallel circuit, the reciprocal of the equivalent resistance is equal to the reciprocal of each of the resistances of the individual resistors. Ohm’s Law - law formulated by Georg Ohm that relates current, voltage, and resistance within a circuit; voltage is equal to current times resistance. open circuit - a circuit with a break, either a switch or malfunction in which current cannot flow. series circuit - a closed loop in which the current follows a single path. voltage drop - loss of voltage due to resistance.
