Kirchoff’s laws - iii All the resistors are six ohms and all the batteries are 12 volts. What is the current through the resistor labeled R? A bit of a summery. Kirchoff’s laws - iii

What’s up? Clouds Quiz Today Exam Next Wednesday Start new topic on Wednesday, after exam. NO REVIEW on Monday. Make sure you do the WebAssigns Same 3x5 index card allowed on the exam. You must actually solve the problem on the exam, not just write the answer down.

The current out of the battery is 8 Amperes and 6 amperes flow through the resistor on the left. How much current flows through the other resistor? A 8 Amperes B 6 Amperes C 14 Amperes D 2 Amperes E Not enough Information

Consider 3A ^ 2A v 5A  6A 8 A

review: Wednesday’s activity

Wednesday you measured voltages around the following circuit: 2W 2W - + Across each bulb is IR=3 x 2 = 6 Volts 12 Volts Let’s Assume These Values

12.0 L H L H L H V=0 L H

-6.0 L H L H L H 12.0 V=0 L H

-6.0 -6.0 Voltage “rise” L H L H L H 12.0 V=0 L H Sum of Voltage RISES around the closed loop = 12 -6 -6 =0 Kirchoff’s Second Law

Let’s Do the Kirchoff Again! R1 = 2.00 Ω R2 = 8.50 Ω

All the resistors are six ohms and all the batteries are 12 volts All the resistors are six ohms and all the batteries are 12 volts. What is the current through the resistor labeled R?

Finish the Kirchoff Experiment
