1. Ohm's Law

A)Use Ohm's law to prove that the equivalent resistance of two resistors in series is Req=R1+R2.

B) Use Ohm's law and the junction rule to prove that the equivalent resistance of two resistors in parallel is Req= (R1^-1 + R2^-1)^-1

1. Using what you know about resistance, current, and Ohm's Law, hypothesize about how parallel resistors would affect current flow. What would you expect the effect of the resistance of two equal resistors in parallel to be on the current flow, compared to the resistance of one alone? -What are the different advantages of a) the series vs. b) the parallel circuits? The resistors could be replaced with lightbulbs or any other household objects including switches and fuses. Can you...

Find the equivalent resistance of a resistive network with three resistors: R1 = 2 Ω (ohm), R2 = 7 Ω (ohm), and R3 = 9 Ω (ohm), where the series combination of R1 and R2 is in parallel with R3. In other words: (R1 in series with R2) in parallel with R3. Quote your answer in Ω (ohm) rounded to one decimal place.
