Module 5: Equipotential Surfaces and Electric Field Capacitors 1. Dry air will support a maximum electric field strength of about 2.0 x 10" V/m. Above that value. the field creates enough ionization in the air to make the air a conductor. This allows a discharge or sport that reduces the field. What, then, is the maximum voltage between two parallel conducting plates separated by 3.5 cm of dry air (4 pts) 2. Calculate the voltage of a battery connected to a parallel plate capacitor with a plate area of 3.0 cm? and a plate separation of 5mm if the charge stored on the plates is 6.0 pC. (4 pts) Module 6: Series and Parallel Capacitors 1. Four capacitors are connected as shown in the figure below. Determine the following: (5 pts) A. Total Capacitance (Cr) B. Total Charge (Q ) C. Individual Charges (Q1. Q2 Q. Q) D. Voltage drop in each capacitor (V1. Va. Va. V.) 2. A voltage of 12 V is placed on a capacitor with C = 85 pF. (a) What is the charge on the capacitor? (b) How much energy is stored in the capacitor? (4 pts)
