Printer Friendly Version
A circuit contains two resistors (10
and 20
) and two capacitors (12 µF and 6 µF) 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 µF 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 your answer.
