Part II: Dielectrics and Capacitance
1a) Click on the "Dielectrics" tab.
1b) Set the plates to the area A between (195-205 mm2), separation d between (7.5- 8.5 mm), maximum positive battery voltage (1.5 V) and minimum dielectric constant (1) with zero offset to begin. See fig. below.
1c) Determine the value of Co = (epsilon_0 * A) / d and compare it to the value from the par chart.
1d) Insert the dielectric material in the capacitor, and determine the value of the capacitance C (in F)
1e) Change the value of the dielectric constant k then complete the following data table (keep the plate separation and area constant through all trials)
1f) Plot a graph of the relationship between (k, C) with k on the x-axis, and find the slope of the line.
1g) Attach the graph to your lab report.
1h) Use the equation, C = kCo determine Co and compare it to the value.
1i) Calculate the percentage error in Co.
