 * Researchers:**

Experimentally find the relationship between the Voltage across an ohmic device and the current flowing through device.
 * Research Question:**

The relationship between the voltage across an ohmic device and current flowing through device is a direct, linear relationship.
 * Hypothesis:**

Power supply Voltmeter Ammeter resistor leads
 * Materials:**


 * Procedure:[[image:Untitled drawing (2).jpg width="498" height="379" align="right"]]**
 * 1) Gather equipment
 * 2) Connect leads to power supply and connect ground to the ammeter
 * 3) Attach resistor to ammeter and the positive from power supply
 * 4) Connect leads voltmeter and the to resistor
 * 5) Turn on power supply
 * 6) Increase current from power supply in increments of 0.02 A from 0 A to .12 A.
 * 7) Collect the data from voltmeter
 * 8) Repeat steps 6 and 7 to gather greater data range

 * Data Analysis:**


 * Conclusion:**

Our data supports our hypothesis. As the voltage was increased, the current increased as, causing a direct, linear relationship.Our slope is 80.05 and y intercept is -726
