Please solve all with steps :((((

1. In the following network of capacitors, C1 = 2 uF, C2 = 1 uF, C3 = 2 uF, and C4 = 1 uF. A 12-V battery is connected to the network as shown. The switch 8 is initially open. (a) With the switch 5 staying open, find the charge on C2; (b) After the switch 5 is closed for a long time, find the energy stored in C4. Cs 2. In the following circuit, (a) Find the equivalent resistance Ra between a and b; (b) Using Rm, and the Kirchoff rules, write down the linear equation set with the currents through the 60 and SO resistors as unknowns; (c) Find the currents through the 60 and SQ resistors; (d) Find the power dissipated in the 30 resistor. 81 = 1V 6
