happens to the light and the heating coil?
b) What happens to the bi-metallic strip?
c) What happens then to the light and the
heater?
d) What happens then to the bi-metal strip?
e) What happens next?
f) What would you see?
g) Where is this used on a car?

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.
