Today started with the difference between putting bulbs and batteries in parallel and in series.

This part of the class was depicting the value of resistance depending of the color

picture of Different resistors 

This is the problem we are trying to solve for displayed below is the diagram 

Problem

100 and 150 are in series therefore we would add them together 250 ohms 

250 and 100 are parallel resulting in 67 ohms 

67 ohms and 100 ohms are in series resulting in 167 ohms 

167 and 75 are in parallel then the result is 51.74 ohms 

Our result from the pictures above proven with 51.9 which is very close to what we had 

Chat of how to solve a diagram 

This is a new diagram now we are solving for the ampere  

We are given three different unknowns. The math is incorrect but our first process was to find I(1) then solve for I(2) then the result of those two will be I(3).
