Find the equivalent capacitance in the circuit below (Assume the capacitors are fully charged). If capacitor C1 = 9 nF and C227 nF. (Hint: Capacitors in series the voltage is divided, and the charge is equal for capacitors.) Voltage of the battery is 5V. a. How much is the voltage at Cl and C2? b. How much is the total charge stored by both capacitors? C. Replacing the circuit with the equivalent capacitor, how much is the electric field if the distance between the plates is 1 mm
