Circuits Exercises

Hello guys!!!! Remember that we are having a test tomorrow so better read your notes tonight because it will help you have great test results. Back to what this blog is all about, Ms. K discussed the hand-outs she distributed last friday. The answers are posted in her slides. Afterwards, she gave us the answers to the exercises but the solutions are not given because she wants us to solve it ourselves. As a feedback, not giving out the solution is a good way to practice what we have learned because it will help us understand the topic more.
The following is from one of our hand-outs. I posted this because this what we need to remember and understand so that we can solve easy and difficult problems.

SERIES AND PARALLEL CIRCUITS

TYPE
OF CIRCUIT

1) SERIES

CURRENT is constant throughout the entire circuit.

POTENTIAL Individual potential drops add up to the total potential drop.
DIFFERENCE

RESISTANCE R_total= R₁+ R₂+ ....

2) PARALLEL

CURRENT Individual currents add up to the total current.

POTENTIAL Potential difference is constant across all parts of the circuit.
DIFFERENCE

RESISTANCE 1/R= 1/R₁+ 1/R₂+ ....

This table summarizes the basics about the series and parallel circuits so if you master this table, solving problems are not as hard as you think it is.

Good luck and Godspeed......(",)!!!!!

Friday the 13th's Physics Class

Hello guys! As you all remember, we went over some exercises and notes in our class. We did less work because Ms. K was not around but a substitute named Ms. McQueen filled in. As a comment for our substitute, she made our friday's class fulfilled because she covered all of the works Ms. K asked her to do. Anyway, this is the list of all the things we did.

1. Go over 8.3
2. Overhead notes
3. Hand-out sheets- Force and spring and Hooke's law
4. On problems p.237-239
nos. 1, 2, 6, 8, 9, 13, 14, 20, 21

We went over the answers for the concept-development 8.3 sheet. (Click the images to see the content larger)

Then Ms. McQueen discussed the overhead notes. The notes was about the derivation of the equation.



Afterwards, she gave us the hand-outs entitled "Force and the Spring". A little explanation of the sheets was discussed to us. Thereafter, we were told to answer the exercises in the book.

That's all what we did last friday and God bless us all in Physics.
