TRIAL RUN 1

Today we did our first run to test whether our setup is correct, and whether the bacteria will produce electricity. Fig 1 is a photograph of our setup.

Materials used: 

-Copper sheets (5cm x 5cm)

-4 insulated wires with crocodile clips

-200 OHm resistor

-Multimeter

-NaCl solution (salt water solution)

-Filter paper

Total duration: 30 mins

Observations:

It was observed that between each transition of increase in electricity generated, there would be slight fluctuation between the values (e.g. when increasing from 2.7 to 2.8 millivolts). As time passed, the period of fluctuation between the values increased, taking a longer time to stabilize.
