Hi , I have a varying voltage and varying current applied to the DC motor . How to measure kwh for this ? . Should we integrate V*I every second or what is the exact procedure.
Thanks
Yes, you have to integrate V*I if both are varying. The interval between measurements will affect the accuracy of the result and should be chosen with regard to the expected rate of variation of V and I.
