A 15 Watt desk-type fluorescent lamp has an effective resistance of 200 ohms when operating (note: the 15 Watts is only associated with the lamp). It is in series with ballast that has a resistance of 80 ohms and an inductance of .9H. The lamp and ballast are operated at 120V, 60HZ. Draw the circuit Calculate the power drawn by the lamp (hint: for R use the sum of both
a. resistances)
b. Calculate the apparent power
c. Calculate the power factor
d. Calculate the reactive power Calculate the size of the capacitor necessary to provide unity power factor
