A biomedical engineer is testing a flexible micro-electrode array designed for localized neural stimulation. The array consists of several identical micro-electrodes connected in parallel to a constant voltage source. During testing, the engineer measures the total current flowing through the circuit as different numbers of micro-electrodes are activated. The results are recorded in Table 1.

Table 1

Number of active electrodes in parallel	Total current in mA	Potential difference in V
8	22.4	4.20
6	16.8	4.20
4	11.2	4.20
2	5.6	4.20

Using data from Table 1, calculate the electrical resistance of only 1 micro-electrode.
