Question

A circuit contains two resistors (10 Ohm and 20 Ohm ) and two capacitors (12 muF and 6 muF) connected to a 6 V battery, as shown in the diagram to the right. The circuit has been connected for a long time Calculate tbc total capacitance of the circuit. Calculate the curent in the 10 Ohm resistor. Calculate the potential difference between points A and B. Calculate the charge stored on one plale of the 6 muF capacitor. The wire is cut at point P will the potential difference between points A and B increase dectreace, of remain the same? _____increase _____decrease ______remain the same justify your answer.

Explanation / Answer

(a) the total equivalent capacitance circuit will be equal 6*12/6+12=4 micro farad (b)I10=6/10+20=6/30=0.2 A (c)Vab=20*0.2=4 V (d)since the charge in a series circuit is equal Q=Ceq*V Q=4*10^-6*4=16*10^-6 C=16 micro columbs (e) will remains the same as the capacitor is open circuited when it is operated for a long time
