1. A battery with an emf 50 V is connected in series with two capacitors. The first capacitor has a value C1 = 10 microF. After the circuit has readied equilibrium the second capacitor is found to contain a charge of Q2=400 microC. Find the value of the second capacitance C2.
2. The circuit below is called a Voltage divider. What value of R will make Vout=Vin/8?
