In the chapter, we shall define the basic active and passive circuit models, explain power conventions and determine when power is delivered and absorbed, state Ohm's law and Kirchhoff's law, determine the equivalent resistance of a passive circuit containing only resistors

14-6 Effective values and power The effective or rms value of the function f(t) is

Example 2: (p175-12) resistor, capacitor, and voltage source=100cos300n are all in series. If the average power dissipated by the resistor is 150W and the rms capacitor voltage is 10v, determine R and C
