Ohm's+law+lab


 * Lab Report - Due in Classroom**


 * Purpose** - Find the relationship between resistance and current and voltage.


 * Materials** - Circuit board and Variable Voltage Supply (include picture of set-up)


 * Data** - Record data on provided sheets. Put onto spreadsheet and cut and paste into document

1. Current vs. Resistance 2. Current vs. Voltage
 * Graphs** -

Determine relationships and straighten as needed.

Determine slopes and formulas. Percent error on slopes of all graphs vs. constant values (voltage or resistance)
 * Calculations**

1. What was the relationships between resistance and current? 2. What is the relationship between voltage and current?
 * Questions**


 * Conclusion -** Regular expectations

FYI - voltages is joules/coulomb ampere is coulomb/second
