Question

Which one of the following correctly lists two ways to decreasing the capacitance from a single capacitor? increase the area of the plates or increase the separation of the plates increase the area of the plates or decrease the separation of the plates decrease the area of the plates or increase the separation of the plates decrease the area of the plates or decrease the separation of the plates If you have a parallel plate capacitor and disconnect it from the battery: the charge and voltage both drop immediately to zero the charge and voltage slowly drop to zero the charge stays the same but the voltage could change the voltage stays the same but the charge could change Calculate the voltage on a 12.0 nF parallel plate capacitor that bolds 1.50 nC of charge. (Show your work, including equations and proper units) the If a current of 1.50 A flows through a section of wire, how much charge flows through the wire in 2.00 ns? (Show your work, including equations and proper units)

Explanation / Answer

2. (c)decrease the area of the plates, increase the separation of the plates.

3.(C) the charge stays the same but voltage changes

4. given ,c=12nF=12*10^-9F
q=1.5nC=1.5*10^-9C

V=C/q=12*10^-9/1.5*10^-9=8V

5.I=1.5A ,   t=2ns=2*10^-9s

q=I*t=1.5*2*10^-9=3*10^-9C
