Predict what will happen to the circuit if R3 burns out. (AKS 8c)
R1 turns off & R2 stays on
R1 stays on & R2 turns off
R1 & R2 both stay on
R1 & R2 both turn off

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
