Question

You are given a 9V battery and two capacitors. The first capacitor has a value of C1 =12 mu F and the second has a value of C2 =60 mu F. If the two capacitors are placed in parallel, connected to the battery and completely charged... What is the equivalent capacitance of the circuit? What is the value of the voltage across capacitor C1? What is the value of the voltage across capacitor C2? What is the value of the charge on capacitor C1? What is the value of the charge on capacitor C2? What is the value of the voltage across the battery? What is the value of the current through the battery?

Explanation / Answer

a)C = c1+c2 = 72 uF

b) voltage1 = 9V

Vc) voltage2= 9V

d) q1 = c1*V = 12*9 = 108 uC

e) q2 = c2*V = 60*9 = 540 uC

f) voltage = 9 V

g) 0 A
