Chapt. 28 Circuits 217 028 qfull 00710 2 3 0 moderate math: charging an RC circuit 11. There is 15 . 0 kΩ resistor and a capacitor in series. The capacitor is initially uncharged. At time zero a constant potential of V 0 = 12 V is suddenly applied across the resistor and capacitor. The potential diFerence across the capacitor rises to 5 . 0 V in 1 . 30 μ s. a) What is the e -folding time or time constant of the circuit? b) What is the capacitance of the capacitor? 028 qfull 00750 2 3 0 moderate math: RC circuit charging disguised 12. HRW, p. 657, Pr. 52. HINT: This problem is easy once you see past the camou±age. 028 qfull 00760 3 3 0 tough math: capacitor bridgeoid 13. Here is a circuit description. There is an emf E . ²rom E ’s positive terminal is a wire connecting E to two vertical parallel circuit segments each with two resistors in series: the left segment going downward has resistors R 1 and R 2 and the right segment going downward has resistors R 3 and R 4 . The segments reunite in a wire that connects to the negative terminal of
