Electronics in easy words
This Section cover Definition of capacitor, working principle of capacitor, basic facts behind capacitor, uses of capacitor, charge discharge and effect of capacitor in circuit.
What is the difference between resistor capacitor and inductor? Resistances dissipate energy in the form of heat, capacitors store energy in an electric field, and inductors store energy in a…
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…
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…
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…
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 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…
Why does the capacitor blocks DC but not AC? a capacitor is like a buffer. you can fill it up to full. because a lot of capacitors are small, the…
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? 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? a charging cap proportional to the applied voltage. low voltage equals longer charge. resistance during charging increases, discharged means lower resistance….
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…
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…
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…
