Express your answer with the appropriate units.Explanation / Answer
Here ,
as the capacitors C1 and C2 are in Parallel ,
The Voltage across them is same ,
as,
V = Q/C
Hence ,
Q1/C1 = Q2/C2
Q2 = 16*7/2
Q2 = 56 uC
the charge on C2 is 56 uC
B)
Now ,
as R2 is in parallel with C1 and C2
V(R2) = V(C1)
V(R2) = 16/2
V(R2) = 8 V
NOw ,using voltage divider
V(R2) = R2*E/(R1+R2)
8 = 3*50/(3+R2)
R1 = 15.75 Ohm
the resistance R1 is 15.75 Ohm
