AS Physics - Internal resistance investigation I will conduct the following investigation with the aim to find the internal resistance of a lemon battery, which I will construct myself. The variables that could affect my experiment are as follows: * Size of lemon - I will conduct my experiment in no longer than an hour, allowing me to use the same lemon for all results * Size of metal electrodes - I will use the exact same electrodes throughout the whole experiment * Length of any connecting wires - I will use the exact same wires throughout my experiment and will not break the circuit once I have started collecting data * Resistance in the circuit - I will vary this using a highly sensitive variable resistor as shown in my method. To make my experiment fair I will only vary the most relevant variable to what I am investigating, which is the resistance in the circuit....
