A capacitor has a capacitive reactance of 300 Ω when
connected to a 60-Hz power line. What is the capacitive reactance
if the frequency is increased to 100 Hz?
2. A pure capacitive circuit is connected to a 480-volt, 60-Hz
power source. An ammeter indicates a current flow of 24 amperes.
The circuit current must be reduced to 16 amperes by connecting a
second capacitor in series with the first. What is the value of the
existing capacitor? What value capacitor should be connected in
series with the original capacitor to limit the circuit current to
16 amperes?
