A circuit two resistors ( 10 and 20 ) and two capacitors (12mF and 6mF) connected to a 6 V battery, as shown in the diagram above. The circuit has been connected for a long time.
a. Calculate the total capacitance of the circuit.
b. Calculate the current in the 10 resistor.
c. Calculate the potential difference between points A and B.
d. Calculate the charge stored on one plate of the 6 mF capacitor
e. The wire is cut at point P. Will the potential difference between points A and B increase, decrease, or remain the same? Justify..
