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 isopotential plane, it has no effect. otherwise the electric field is changed. Think of it as a change in the geometry of the plate. if … Read more

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 it has the same voltage as the source, after which there will be no more potential difference and therefore no current, it will behave like … Read more

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 property of polarizability, a conductive material will turn it into a resistor. There are only two types of ideal electrical materials. insulators and conductors. insulators … Read more

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 capacitor’s battery when the capacitor is fully charged. however;) in steady state, the capacitor behaves like an open circuit, so the current 0. the equilibrium … Read more

Is it possible to charge a capacitor at any potential

Is it possible to charge a capacitor at any potential? only until the working voltage. beyond that, it causes a breakdown. you can charge a capacitor at any potential as long as the charging voltage is lower than the nominal voltage value of the capacitor. yes, but you must apply a higher potential than the … Read more

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 and they have a limited speed at which they can travel. therefore, it takes time for the charge to change, no matter how large the … Read more

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, or very weakly insulated from the voltage. this is done for security and can only be implemented in certain types of circuits. The premise of … Read more

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 absence of current, so that for a capacitor to be in series with a steady-state circuit, it must be either fully charged, or open, which … Read more
