Let dq be the differential charge, dw be the differential energy. The rate of change of energy with time is given as:

• A. \(\frac{{dw}}{{dq}} \times \frac{{dq}}{{dt}}\)
• B. \(\frac{{dw}}{{dq}} + \frac{{dq}}{{dt}}\)
• C. \(\frac{{dw}}{{dq}}/\frac{{dq}}{{dt}}\)
• D. \(\frac{{dq}}{{dw}} \times \frac{{dq}}{{dt}}\)
