I don't understand what formula to use for this question:
Points A and B each have an electric potential of +9 V. How much work is required to take 1 mC of charge from A to B?
Thank you
exactly as much as to slide down one mountain and up the one beside it to the same height, with no friction of course.
ps:
That is what potential is all about.
Thanks, I'll keep checking with others for a formula. Appreciate your time.
To calculate the work required to move a charge from one point to another in an electric field, you can use the formula:
Work (W) = Charge (Q) * Potential Difference (ΔV)
In this case, the charge (Q) is given as 1 mC (which is equivalent to 0.001 C), and the potential difference (ΔV) between points A and B is 9 V. Therefore, we can substitute these values into the formula:
W = 0.001 C * 9 V
To calculate this, simply multiply 0.001 C by 9 V:
W = 0.009 J
Hence, it would require 0.009 Joules of work to move 1 mC of charge from point A to point B.
