1. A capacitor of parallel square plates of 130 cm have a separation between them of 3.5 mm. Determine (a) the capacitance and (b) the charge on each plate if it is connected to a potential difference of 12 V. 2. Determine the energy stored in a capacitor of capacitance 144 pF and connected to a voltage source of 100 V. 3. Determine the equivalent capacitance between points a and b, if C = 5.0 F, C = 8.0 F, and C = 6.0 HF. You can't calculate the total capacitance in one step, if you do that you will have 0. You need to show the equivalences in different calculations. 4. Using the above circuit, find the total charge and total energy of the circuit if V = 20 V
