What is the impedance of a series combination of a 50-ω resistor, a 5.0-μf capacitor, and a 10-μf capacitor at a frequency of 2.0 khz?
Answers: 2
= Capacitance of first capacitor = 5.0 x 10⁻⁶ F 
= Capacitance of second capacitor = 10 x 10⁻⁶ F 
= Series combination of capacitance
= capacitive reactance of series combination
