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…

Does direct current pass through the capacitor?

if a capacitor is initially not charged and someone uses the voltage as it is, induction will cause the capacitor to fill to the level of the applied voltage, therefore…

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…

What is the function of a capacitor in a fan?

The fan has an AC motor. Now, when a capacitor is added to the additional auxiliary winding of the stator, a field is created which goes 90 degrees to the…

How does a MOSFET input behave like a capacitor Does this make a different application to a BJT

The transistors both fet and bipolar have a capacity across all their junctions. it is simply the resistance of the network that is so high that makes it significant for…

If you measure the voltage of a capacitor does it discharge or have an effect on the capacitor

What happen when Measure the voltage of a capacitor it would discharge the capacitor according to the input impedance of the meter. the higher the input impedance, the less the…

What is a steady state current in a capacitor For what condition is it zero

What is a steady state current in a capacitor For what condition is it zero? Stationary current, as its name implies, means current flowing through the circuit of the single…

Why cant you use a conductor in a capacitor instead of a dielectric medium

Why cant you use a conductor in a capacitor instead of a dielectric medium? A capacitor needs a capacity to store energy, which means that a dielectric material having the…

When a voltage source is connected to a capacitor is it an open circuit

voltage source is connected to a capacitor if your source is alternative, then the capacitor will charge and discharge, charge and discharge. source is continuous, then it will charge until…

What happens when we put a conductor between the plates of a capacitor

What happens when we put a conductor between the plates of a capacitor? insertion of an otherwise unconnected conductor introduces an isopotential surface. if it is inserted into an existing…

Why does a capacitor offer infinite resistance at steady state

Why does a capacitor offer infinite resistance at steady state? the circuit conditions for a stable state are either the absence of a change in the circuit current or the…

Generally why are one of the two plates of a capacitor earthed

Generally why are one of the two plates of a capacitor earthed? if it is grounded, it is because the capacitor housing is either directly connected to this grounded plate,…

Why cant voltage across a capacitor change instantaneously

Why cant voltage across a capacitor change instantaneously? To change the charge in a capacitor, you must either add or remove electrons from the plates. these electrons have a mass…
