Part A Two 4.0 cm x 4.0 cm square aluminum electrodes, spaced 0.60 mm apart are connected to a 400 V battery What is the capacitance? Express your answer using two significant figures. Submit My Answers Give Up Incorrect Iry Again, 2 attempts remaining Part B What is the charge on the positive electrode? Express your answer using two significant figures Submit My Answers Give Up Incorrect Iry Again, 4 attempts remaining

Explanation / Answer

given are

area =4cm*4cm

=0.04*0.04m^2

=0.0016m^2

d=0.6mm=0.6*10^-3m

V=400V

C=eoA/d

8.85 . 10^–12*0.0016/0.6*10^-3

=0.0236*10^-9

C=23.6pf

b)Q=CV

=23.6*10^-12*400

=9440*10^-12

=9.45*10^-9C
