Series Circuits Wednesday, February 5, 2014 Wednesday, 2/5 – Series Circuits/Ohms Law Respond to the following in your notes: 2Ω 24 v 2Ω 2Ω Use the diagram to: 1.Calculate RT 2.Calculate IT Upcoming Dates: Series circuit quiz on Thursday, 2/6 Week of 2/10 ‘Kindness Week’ Quiz on Wednesday, 2/12 Electricity test on Wednesday, 2/19 Kirchhoff’s Rules Loop Rule: The sum of the potential differences (voltage) around any closed circuit loop is zero. Unit Overview Types of Electricity Dynamic Direct Current (DC) Series Static Alternating Current (AC) Parallel Complex Question 1 What is the resistance of an electric frying pan that draws 12 amps of current when connected to a 110V circuit? Question 2 How much current is drawn by a 25 Ω lamp when a voltage of 12 v is applied? Question 3 What is the voltage of a battery if it produces a current of 0.75 amps in a 12 Ω resistor? Question 4 a. Like charges ____________ and opposite charges __________. b. T or F: Friction can cause charge separation c. What causes electrons to be stripped from one material and added to another? Question 5 Draw a series circuit that includes the following: 1. Total voltage of 90 V 2. Total current is 5 amps 3. Three resistors of equal value Question 6 Draw a series circuit that includes the following: 1.Total current of 2 amps 2.Total resistance of 20 Ω 3.Two resistors of equal value
