Question

A variable frequency a.c source is connected to a capacitor .How will the displacement current change with decrease in frequency ?; As conduction current decreases , frequency decreases As conduction current increases , frequency decreases There will be no chargeAs conduction current decreases , frequency decreases initially and then increases

Answer 1

he frequency And the current through capacitance are directly proportional. So on decreasing frequency the current tend to decrease too.

But not always. Only when ideal capacitance is assumed. Practically, a capacitane has inductance properties also, esp after resonance. This resonance frequency is mentioned in the data sheet and can be properly selected
