voltage, equivalent capacitance, and stored energy problem

A. Calculate the equivalent capacitance of the following group of capacitors. B. Calculate the voltage across each capacitor, the charge separated in each, and the stored energy in each. see attached

Net potential problems

The following questions refer to the attached diagram. Charge q1, q2, and q3 are fixed in place. Points A and B lie on the line y=x. Point A is midway between charges q1 and q3. Point B is twice the distance from the origin as point A. Note: charges q1, q2, q3 and point B lie on the corners of a square, with point A at the center. Assume there is no gravity in this problem.

524- Electricity Magnetisma and Waves

CMP is installing a new transformer to supply power to my woodworking shop. Its primary side has 200 turns (110 volts), and its secondary side had 500 turns. It supplies power to the following circuit: (refer to attachment). CMP charges me $0.015 per kWhr. My scroll saw (item R3) runs for 45 hours per month. What is my monthly charge for running the scroll saw?
