Question details

Date 1217ulre Tech Lab CONCEPTUAL PHYSICS Hewitt/Baird Remove the voltmeter and add the Electric Field Detector. Check Show values on the detector 4 What is the electric field outside of the area directly between the plates? a. How does the electric field change as you move from the positive to the negative plate? b. s. The above questions should be consistent with what you already know about capacitors. Summarize the relationships you saw in questions 1-4 below. (Remember up to this point you have NOT changed the capacitance) a. Relationship between charge and voltage for constant capacitance b. Two pieces of evidence for Sa: Now, you will investigate physical factors that affect the capacitance. There are green sliders for plate area and separation. Predict and then find the relationship between a change in these values and the capacitance. 6. Prediction Actual Relationship Plate Area Plate Separation 7. Write a proportion (not an equation yet) that reflects the relationships you discovered in #7
Finally, we will investigate the effect of a dielectric materiol. A dielectric material is 8 Go to the Dielectric tab. Add a capacitance meter, plate charge meter, and material in between the plates, and increase the battery voltage to-15V some substance that is placed between the two plates voltmeter to the simulation. Use the greenOffset slide r to move the dielectric a. List two quantities that increase with the addition of the dielectric b. What quantity remains the same? Different materials have different effects when used as a dielectric. The degree to which a material affects (eventually) capacitance is referred to as its dielectric constant. Use the slider to control the dielectric constant in order to establish the following relationships for a constant voltage 9. a. Dielectric constant and capacitance b. Dielectric constant and charge stored 10. Use your answer to 9a to incorporate the dielectric constant into the proportion you found in #7. Use a K (lower case kappa) to represent the dielectric constant.
