7/21/09 LAU/PHYS 1302 Chapter 24 12-2 AC Circuits (Summary) s AC Voltage is a sinusoidal (sine) function of time . s Resistors behave as in DC circuits. s Capacitors and inductors behave differently; current and voltage are in general out of phase . s Circuits with R, C and L are mathematically complicated because Kirchoff’s Laws apply to instantaneous currents and voltages : adding trigonometric functions. s Phasor diagram is a graphical method for adding and subtracting trigonometric functions visually. s Ohm’s Law applies to rms values in AC circuits with R replaced by impedance (Z) which depends on C, L, and ω . s RLC circuits are mathematically similar to a spring-mass system with friction .
