# Construction of the Stand and Experimental Studies of the Iontophoresis Process
## 5 Analysis of Test Results  
The power consumption \(I_{p}\) changed depending on the voltage \(U\) at the power supply output and the temperature \(T\) of the solution. Chemical reactions such as sediment precipitation and tarnishing on the electrodes were observed, suggesting the movement of electrons towards the cathode and anode. The resistance \(R\) of the solutions was highest at the lowest voltage \(U\). The program Statistica version 14.1.0.4 was used to statistically evaluate the results. For the purposes of data analysis, for the current intensity \(I_{p}\) of the solutions, the test results were rounded to the thousandth. Table 1 shows the results of the research. The graphs presented in Figure 5 were developed on the basis of a regression analysis. The conducted analysis clearly showed a relationship between the temperature \(T\) of the solution and the current \(I_{p}\). This relationship is described by quadratic dependencies. It was found that, for case (a), an increase in the temperature \(T\) of the solution causes a decrease in the current \(I_{p}\) of the electrolyte in the range of 26-30 \({}^{\circ}\)C. However, as the temperature \(T\) of the solution increases within the range of 34-40 \({}^{\circ}\)C, the current \(I_{p}\) increases. Thus, there is an extreme minimum at a temperature of about 32 \({}^{\circ}\)C. Therefore, there is an extreme minimum at a temperature of around 32 \({}^{\circ}\)C. However, for cases (b), (c) and (d), it was observed that when the temperature \(T\) of the solution increases in the range from 26 to 32 \({}^{\circ}\)C, the value of the electrolyte current \(I_{p}\) increases, reaching an extreme for the electrolyte temperature \(T\) of about 32 \({}^{\circ}\)C, and then the current value \(I_{p}\) decreases. The maximum value of current \(I_{p}\) of the electrolyte was approximately \(I_{p}=120\) mA and the minimum \(I_{p}=0.3\) mA. From the conducted study, it is clear that a voltage \(U\) on the electrolyte supply of more than 1 V causes a significantly higher movement of electrons. The increased movement of electrons contributes to an increase in the absorption of medicinal substances. Figure 6 presents the influence of the temperature \(T\) of solution no. 2 on the current \(I_{p}\) in the electrolyte. Figure 7 presents the influence of the temperature \(T\) of solution no. 3 on the current \(I_{p}\) in the electrolyte:  
The regression analysis showed a correlation between the temperature \(T\) of the solution and the current consumption \(I_{p}\) by the electrolyte. This relationship is described by the quadratic function shown in Figure 6. It was found that, for case (a), an increase in the temperature \(T\) of the solution results in an electrolyte current density \(I_{p}\) decreasing in the range of 26-32 \({}^{\circ}\)C. However, as the temperature \(T\) of the solution increases within the range of 34-40 \({}^{\circ}\)C, the current intensity \(I_{p}\) increases. Therefore, there is an extreme minimum at a temperature of approximately 34 \({}^{\circ}\)C. It has been observed that, for case (b), in the temperature range \(T\) of 26-30 \({}^{\circ}\)C for the electrolyte, the current intensity \(I_{p}\) of the electrolyte increases, while, in the range of 36-40 \({}^{\circ}\)C, the value of the current intensity \(I_{p}\) of the electrolyte decreases. The extreme maximum for variant (b) was reached at a temperature of 36 \({}^{\circ}\)C. However, in cases (c) and (d), it was observed that, with an increase in the temperature \(T\) of the solution in the range from 26 to 34 \({}^{\circ}\)C, the value of the electrolyte current intensity \(I_{p}\) increases, reaching an extreme for the electrolyte temperature \(T\) of about 34 \({}^{\circ}\)C, and then the current value \(I_{p}\) decreases. The maximum value of the current intensity \(I_{p}\) of the electrolyte was reached at approximately \(I_{p}=56\) mA and the minimum at \(I_{p}=0.06\) mA.
