Current × potential difference equals
WebNov 12, 2024 · Electric potential difference is a measure of the amount of potential energy at a given location in a circuit. The concept is also known as "voltage" and is typically measured in "volts." WebApr 8, 2024 · Scan rate impact on the peak current and potential. CVs obtained for 0.1 µM of IC in 0.2 M buffer solution of 6.5 pH on the PNNMCPE by varying the scan rate from 0.05 V/s to 0.25 V/s, has been illustrated in Fig. 7a. The oxidation peak potential obtained for the increased scan rates exhibits continuous shift towards the positive direction.
