The effective value of any periodic current is equal to the value of the direct current which flowing through a resistance R, delivers the same power to r as periodic current does

Example 1: If 0=4v2 cos\tV, Z=2/600Q2 Find p(t)and P. Solution:

《电路》（英文版）9-1 Instantaneous power

Ohm's law states that voltage across many types of conducting materials is directly proportional to the current flowing through the material. U= Ri or R= i R--resis tance()( linear resistor) The resistor is a passive element that cannot deliver power or store energy
