Chann the rl nergy tre a charging event, LIBs can self-discharge 1 to 2 percent each month. Topics Covered in Chapter 22 22-1: Response of Resistance Alone 22-2: L/R Time Constant 22-3: High Voltage Produced by Opening an RL Circuit 22-4: RC Time Constant 22-5: RC Charge and Discharge Curves 22-6: High Current Produced by Short-Circuiting RC Circuit 2007 The McGraw-Hill Companies, Inc. is the current in an RL circuit when switched on (Note the similarity to the exponential behavior of the voltage on a charging capacitor). Use the same amplitude for the square-wave source, but set the frequency to 2000 Hz. For example, RC and RL circuits are commonly used as filters (taking advantage of the fact that capacitors tend to pass high frequency signals but block low frequency signals, while the opposite is true for inductors). Since this lasts for only a "short" time, this is known as a transient effect. •Uncharged capacitors act like a “short”: V C=Q/C=0 •Fully charged capacitors act like an “open circuit”. Integration is a summing process, and a basic integrator can produce an output that is a running sum of the input under certain conditions. Show at least two intervals. The circuit current when voltage first appears in the input is dependent on the resistor.
