How much energy remains when its charge has decreased to half its original value? 1. 4.575 2. 3.7 3. 2.275 4. 3.1 5. 1.4 6. 2.4 7. 2.125 8. 1.45 9. 3.55 10. 1.725 voltage across the resistor drop to V resistor = 6 . 5 V? Consider the circuit, below, where the ca- pacitor is initially uncharged and the switch is open. 29 Ω 11 . 9 μ F 21 V S How long after the switch is closed does the voltage across the resistor drop to V resistor = 6 . 5 V?
Version 081 – mid2 58010 – yeazell – (58010) 2 003 10.0points A long inner cylinder with radius R 1 and an outer cylindrical shell with inner radius R 2
and outer radius R 3 are concentric as shown. These cylinders extends out perpendicular to the plane shown. The charge on the inner cylinder per unit length is λ > 0 and the
