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.

Unit 5 Segment G: 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.

Learning Objectives

-Understand that the total current in a series circuit is equal to the current in each resistor in the circuit.

-Understand that the total voltage in a series circuit is equal to the sum of the voltages of the individual resistors in the circuit.

-Understand the difference between an open circuit and closed circuit.

-Calculate the equivalent resistance for a series circuit.

-Determine the voltage, current, and resistance for a total series circuit and for individual resistors within that series 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.

Georgia Standards of Excellence

SP5
Obtain, evaluate, and communicate information about electrical and magnetic force interactions.
d
Plan and carry out an investigation of the relationship between voltage, current, and power for direct current circuits. (Clarification statement: Application of Ohm’s Law to different circuit configurations, not limited to parallel and series, and calculations of equivalent resistance are expected.)
