Can we use capacitor in place of battery?

Can we use capacitor in place of battery? Since an electric field is present in the capacitor, energy is also stored in the capacitor. A capacitor can obviously be used…

Why are dielectrics used in capacitors?

dielectric is used in a capacitor to isolate two capacitor metal plates. in a dielectric material if you apply a voltage through it then no current will pass through it…

How to measure how charged a capacitor is

How to measure how charged a capacitor is voltmeter. measure the DC voltage across it. Just remember that measuring the tension will start to decrease it. capacitor is just like…

What is a displacement current in a capacitor

What is a displacement current in a capacitor? consider a capacitor consisting of two plates with nothing between them, with air as dielectric between them and now consider that a…

Why does a capacitor store energy but not charge

Why does a capacitor store energy but not charge? capacitors store the separation of positive and negative charges. this is equivalent to indicating that they store an electric field and…

Why does a capacitor take infinite time to charge

Why does a capacitor take infinite time to charge? a charging cap proportional to the applied voltage. low voltage equals longer charge. resistance during charging increases, discharged means lower resistance….
