Electromagnetism Midterm: The Banuk’s blue light EPCC 1. Calculate the effective resistance and overall current in figure 1. Label where the anode and cathode are, and the proper direction of current. 2. Calculate the effective capacitance in figure 2. Calculate the new effective capacitance if you place strontium titanate between each capacitor. 3. Review the plot of two resistors in figure 3. Describe the behaviors and characteristics of these resistors. For the ohmic resistor, calculate its length if it is made of iron, remains at room temperature, and has a cross-sectional area of 1.20x10-9 m2. 4. Calculate the electric field of a parallel plate capacitor with 10.0J of potential energy, capacitance of 0.020 F, and 0.010 m of separation distance between the plates. Refer to figure 4a and 4b (switch closed) for problem #4 5. Calculate the effective capacitance of figure 4a, and determine type of capacitor configuration. Calculate the capacitance for 4b. What would be the dielectric constant needed for it equal the effective capacitance in 4a? What type of dielectric could it be?
