1. For this section use the simulation in the Introduction Tab. Slide the voltage to maximum, tick the boxes Electric Field Lines, Plate charges and Capacitance. What is the effect of each of the following on capacitance separately:
- Reduce the separation distance by half
- Double the area
- Doubled the value of \( d \)
- Double the potential across the plates
Explain your reasoning for each answer above.
2. For this section use the simulation in the Multiple Capacitors Tab. Click on three capacitor in series button.
a. Move the voltage slide to maximum and measure the voltage across the battery with the voltmeter. Vmax=???
b. Change the settings on the 3 caps to :
\( C_{1}=1.0 \times 10^{-13} \mathrm{~F} \)
\( \mathrm{C}_{2}=2.0 \times 10^{-13} \mathrm{~F} \)
\( \mathrm{C}_{3}=2.5 \times 10^{-13} \mathrm{~F} \)
c. Now measure the voltage across each capacitor.
\( \mathrm{V}_{1}= \) ??? \( \quad \mathrm{V}_{2}= \) ??? \( \mathrm{V}_{3}= \) ???
d. What is the relationship of voltages?
e. Using the stated capacitance \( \left(1.0 \times 10^{-13} \mathrm{~F}, 2.0 \times 10^{-13} \mathrm{~F}, 2.5 \times 10^{-13} \mathrm{~F}\right) \) find the charge on each capacitor.
