Question

A capacitor is connected to the terminals of avariable frequency oscillator. The peak voltage of the source inkept fixed while the frequency is increased. Which statement istrue?
a. the rms current through the capacitordecreases b.the rms current through the capacitorincreases    c. the phase angle between the current andsource voltage changes d. the current becomes zero when thefrequency is large enough
a. the rms current through the capacitordecreases b.the rms current through the capacitorincreases    c. the phase angle between the current andsource voltage changes d. the current becomes zero when thefrequency is large enough

Explanation / Answer

Irms = Vmax/2XC= Vmax/2*2fC so frequency is inversily proptional toIrms    frequency incresed means,the rms current throughthe capacitor decreases
