Question

A circuit element is added to an ac circuit. If the frequency ofthe oscillating voltage across this circuit element is increasedwhile the voltage amplitude remains constant, the amplitude of thecurrent though the circuit element decreases.

What sort of circuit element is this?


an inductor a capacitor a resistor either a resistor, an inductor, or acapacitor either a resistor or a capacitor, but not aninductor either an inductor or a capacitor, but not aresistor either a resistor or an inductor, but not acapacitor
an inductor a capacitor a resistor either a resistor, an inductor, or acapacitor either a resistor or a capacitor, but not aninductor either an inductor or a capacitor, but not aresistor either a resistor or an inductor, but not acapacitor

Explanation / Answer

either an inductor or a capacitor but not resistor because = XL = L                 f = XL/2L XC = 1/C f = 1/XC * 2 *C from the above two cases L and C are inversilyproptional to frequency
