Heyy, so today we started off by Mr. Wirth reminding to scribes to always be alert! Well this one obviously was, because I remember that we started off with a review sheet he handed us...
We did about 4 problems on the sheet that reminded us of the properties of this unit.
We calculated the amount of charge passing through resistor (R2) in 60 seconds. We did this by using I=delta q/T
Next we learned how to draw a parallel circuit using the ammeter symbol, battery, and 2 resistors of a certain ohm.
Lastly we calculated the equivalence resistance of the circuit by using the equation 1/Req=1/R + 1/R2...
After reviewing these concepts we jumped right into notes...
VOLTMETER: measures potential difference between two points in a circuit.
**these are connected in PARALLEL
**extremely HIGH internal resistance
**draws extremely SMALL current
AMMETER: measures current through ONE point in a circuit...
**connected in SERIES
**extremely LOW internal resistance
**creates extremely SMALL voltage drop
so that was all the notes did for the day... by the way ellen missed all of this because she was not here. so i hope she takes full advantage of this blogging experience...
ok peaceout
