Question

Part D Introduction to Capacitancee Now find the capacitance C of the parallel-plate capacitor. Express C in terms of quantities given in the introduction and constants like Eo ning Goal: To understand the meaning of capacitance and ways of calculating capacitance When a positive charge q is placed on a conductor that is insulated from ground, an electric field emanates from the conductor to ground, and the Figure 1 Submit My Answers Give Up Part E Consider an air-filled charged capacitor. How can its capacitance be increased? Increase the charge on the capacitor. Decrease the charge on the capacitor. Increase the spacing between the plates of the capacitor. Decrease the spacing between the plates of the capacitor. Increase the length of the wires leading to the capacitor plates Submit Hints My Answers Give Up Review Part Correct

Explanation / Answer

potential difference = V = E*d

capacitance = q/V = q/Ed <<-----answer

electric field between the two charged plates = E = sigma/eo = q/Aeo

V = Ed = qd/Aeo

C = q/V = eo*A/d

-----------------

capacitance depends on eo , A , d

as the d decreases the C value increases
