2.8 Signal waveforms cont.

Example 2-3 cont.

The average voltage is: Vave.= W/Q = 1.44 kJ./24C. = 60 J/C \ Vave.= 60 V. (in what sense is this the voltage’s average?)

Equating the lamp’s energy to the resistor’s energy yields: Plamp ´ Tlamp = 1.44 kJ. = W5W (where Plamp= 60 W. = 60 J./Sec.)

Ergo, Tlamp = 24 Seconds
