Batteries

March 14th

In the beginning of class, we discussed the advantages and disadvantages of parallel and series circuits.

We talked about batteries and the necessary parts of a battery and how it works.
1. An electrolyte
2. a cathode (metal)
3. an anode (metal)

Next we attempted to make different kinds of batteries and read the amount of volts the batteries produces with a voltmeter.

1. Lemon batteries
2. Coke batteries
3. Vinegar batteries
4. Potato batteries

We connected potato batteries to turn on a light bulb. Unfortunately we didn't get it to light up. According to the voltmeter we produced 2.5 volts, which should be enough to light up the light.
