equivalent to the sum of the voltage drops in that loop. In other words‚ the algebraic sum of the voltages (Vk) in a closed loop is equal to zero (Eq 2). (Eq 2) Equations (1) and (2) are interrelated‚ and this can be demonstrated through modeling a basic electrical circuit involving a second order‚ linear differential equation. For our basic circuit‚ we will use a single closed loop involving one voltage source‚ one resistor‚ one capacitor‚ and one inductor. First‚ it is important to establish

points chosen from all the data collected over the entire 200 seconds. As with the chart‚ it can be seen in the Absorption vs. time graph that light absorbed in the food coloring over time decreases. To find the concentration of the solution the equation for Beer’s law was used. Knowing A‚ є‚ and b‚ it was possible to solve for c and graph the points in the Concentration vs. time graph. This graph shows that over time the concentration of the food coloring is decreasing in the bleach. This function

word FLUX roughly means FLOW. So based on this idea we can define the ELECTRIC FLUX as the ELECTRIC FEILD through a SURFACE AREA. Since the area vector is defined as perpendicular to the surface and the electric field goes through it‚ we define this equation as a dot product‚ similar to the work function. Φ E = E • A = EA cos θ dΦ = ∫ Eda A differential amount of flux is the cross product between the electric field and a differential amount of area. Since you want the total flux‚ you integrate to
