The voltage across two points in an electric circuit is 1 423 mV. A charge of 2 748 mC moves between these two points when a power source does work on the charge.
Determine the amount of work done by the power source.
(a)
Work done (W), potential difference (V), and charge moved (Q) are three variables used in electric circuits calculations.
Which one of the following equations correctly represents the relationship between these quantities?
Q=VW
Q=W⋅V
