- The current through and voltage across an elementvary with time as shown in the figure. Sketch the power delivered to the element for?>0. What is the total energydelivered tothe element between ?=0and ?=25?? The element voltage and current adhere to the passive sign convention.SolveInterpret In (AVR) = In (AV) -t as y(t)=b+mt T and get the result: graph of In (AVR) versus / (called a semi-log graph) should be linear with y-intercept b = ln (AV) and slope m = 1 =-²/ T We can determine t and hence C from an experimental measurement of the slope. Draw a graph of In (AVR) (log of measured voltage across the resistor, vertical axis) vs time (horizontal axis). From the y-intercept of the best-fit line, find AVo = 9[V], as expected. Using the slope, find T = Using this calculate the unknown capacitance: T Cexperimental R - - 1 slope = Now, measure the actual value of the capacitance with the digital multimeter and compare it to the value obtained from the graph: Actual capacitance is: 12,4 FI
