Question:

Describe the ohm's law experiment

Author: Marilyn Bob-Manuel 3ekt



Answer:

Set up a circuit with a dc power supply, a resistor and ammeter in series and a voltmeter in parallel to the resistor. set power supply to 1V and turn it on. measure the current through the resistor with ammter. measure the voltage across the resistor with a voltmeter note these values in a table repeat steps 3-5 increasing the pwoer supply by 1V each time until you reach 10V draw a graph of voltage on y axis and current on x axis compare the graphs gradient with the resistor values repeat for other resistor values If the lines gradient matches the value of the resistor then Ohm's law has been verified.
