State four factor affecting current sensitivity of a moving coil instrument

Edit the post so i can see the letters for each answer, and increase the points required so i'd be able to answer it.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

The answer is: 6.3mi got it right

Amicroscope, because these cells are so small that you would not be able to see them, or what they attack without it.
