SUMMARY

The discussion centers on the transfer of charge between two capacitors, C1 (0.05 µF) and C2 (0.1 µF), in a parallel circuit connected to a 0.4V battery. Initially, C1 is fully charged with a charge of 2 x 10^-8 C. Upon connecting C2, the percentage of charge transferred from C1 to C2 is calculated to be 70%, not 100% as initially assumed. This discrepancy arises from the differing capacitances and the resulting voltage across the capacitors after connection.

Homework Statement


Hi,

I have 2 capacitors c1, c2

c1=.05 uF
c2=.1 uF

Q=CV

c1 is fully charged and connected to a .4V battery in a parallel circuit
c2 is uncharged

c2 was unconnected initially to c1 but once joined c2 can receive a charge from c1.

charge on C1=2 X 10^-8

what is the % charge transferred from c1 to c2 once joined in the circuit

Homework Equations


Q=CV

The Attempt at a Solution



I thought the answer is 100% but it is 70%.

I don't get it?
