Chapter 9 – Circuits and Powers Study Guide

Key Vocabulary:

Junction point Watt Parallel circuit Electric power Series circuit Power rating Power Kilowatt-hour Joule Ohm’s Law Resistance

Things to know:

Identify the difference between series and parallel circuits Draw and recognize series versus parallel circuits Determine the voltage consumed at each load in a series or parallel circuit Determine the current in a wire within a series or parallel circuit Determine when resistance increases or decreases if placed in a series versus parallel Calculate electrical power, current, and voltage using the formula, P = IV Calculate energy consumption

o Be able to convert units Calculate how much you will pay for electricity use
