Please help me answer questions #1-7 on the review sheet. Thank you!

1. (2 points) Why do we draw electric field lines perpendicularly to equipotential lines? Explain what each of them mean. 2. (2 points) Draw the equipotential lines and electric field lines for bar shaped electrodes with a 5 V battery connected to them. One bar will be positive, and one will be negative. 3. (2 points) How do we measure things like voltage, current, and resistance in a circuit? What equipment do we use, and how? 4. (3 points) How would you get the maximum possible capacitance out of a given parallel plate capacitor? (Think of formulas!) 5. (3 points) How does adding a dielectric change the capacitance of a parallel plate capacitor?CA = 200 AF C2 = 6000 HF C3 = 6500 HF C1 = 500 HF V = 12 V 6. (4 points) Calculate the equivalent capacitance of the given circuit. 7. (4 points) Calculate the total stored energy in the same circuit
