Description
When connecting a voltage source to a conductor, an electric field is created from the source's applied potential difference, exerting forces on charges within the conductor. [1] The flow of charges is proportional to the voltage, a relationship known as Ohm's Law. This law also states that the flow of current in a device is inversely proportional to the resistance of the device itself, which depends on its shape, size, and material. Resistance can also come from external sources, which when placed in a series circuit, combine with a device's internal resistance to create a larger load. In this experiment we tested how increasing external loads affect the performance of Duracell CR2016 batteries. To determine its effect, we analyzed its current, voltage, and battery capacity.
