a) What is the electric field between the plates?
b) What is the capacitance of the capacitor?
c) What is the charge on the capcaitor?
2) Two capacitors of capacitance 6.00 microFarad and 8 microfarad are connected in parallel . The combination is then connected in series with a 12.0-V voltage source and a 14.0-uF capacitor.
a) What is the equivalent capacitance of this combination?
b) What is the charge on the 6.00-uF capacitor?
c) What is the potential difference across the 6.00-uF capacitor?
