[[Image:Resistor_seriesWorking in pairs, wire up the circuits and verify the voltages and currents you calculated for circuits 1-5 in last week's homework. Get help from your TA in determining which resistors are which using the resistor color code. The color code is described on the back side of the first page in the Scherz book.png | 200px]]

We have a 5 Volt supply and a 10 Ohm Resistor.**The resistor is rated at 1/4 of a Watt = , or 0.25 WattWatts. **P=I*V. P=I*5V. 10 Ohm resistor* this amounts to a brief (and cautionary) demo of what a '''power rating''' is, and why it is important.
