RC and RL Circuits Study Guide Exponential Functions In physics, most exponential functions are governed by a which has units of time. time constant The following graph shows a typical exponential decay:      (Exponential Decay) Sometimes an exponential function approaches an equilibrium value . In this case, it is the max difference that decays exponentially:   max     max max max  (Approaching ) In some cases, it may also help to use the following derivative formula:     

Outline Section 28.7: RC Circuits A is a circuit with a resistor and a capacitor. It may also have a battery or other RC circuit voltage source. The current in an RC circuit always dies away over time:        where For an RC circuit without a battery, the voltage across the capacitor and the charge stored
