Physics 2212 Homework 6 (due: April 12) 1. What is the equivalent capacitance between points A and B? 2. The electric field inside a 30-cm-long copper wire is 0.010 V/m. (a) What is the potential difference between the ends of the wire? (b) What is the current in the wire? The diameter of the wire is 0.5 mm. 3. A 50-cm-long gold wire is connected across the terminal of a 12 V battery. If the current in the wire is 2.0 A, what is the wire’s diameter? 4. What is the magnitude and the direction of the current in the 10 Ohm resistor shown in the figure? 20 μF A B 30 μF 25 μF 40 μF 30 μF 10 8 V 4 V 20 5 V
