What is the purpose of a capacitor in an AC circuit? During this charging process, a charging current (i) will flow to the capacitor opposite any voltage change at a…

How do you jump start a positive ground vehicle? A jump start, also known as boost, is a method to start a vehicle with a booted discharge battery. A temporary…

Can current be negative? Can current be negative? As from question you thought that its wrong, but no friend question is right but current is never negative but its calculation…

How is a capacitor different from a battery? Batteries and condensers seem similar because they store and release electricity. However, there are key differences between them that affect their potential…

Can there be a potential difference without current? The electric potential is the potential electric power per unit charge, measured in joules per coulomb (volts). The “electric potential” must be…

What would happen to the voltage if you increase the resistance or what is varistor? A varistor is an electronics component with an electrical resistance that varies with applied voltage….

What happens to a resistor when it fails? A fixed composition resistor normally fails in an open configuration when overheated or too demanding due to shocks or vibrations. Excessive humidity…

What happens when a resistor is short circuited? A short circuit is an abnormal connection between two nodes of an electrical circuit designed to be at different voltages. This results…

What is a pure inductor? Inductors do not behave just like resistances. While the resistors simply oppose the flow of electrons through them (by lowering a voltage directly proportional to…

Why do you use a resistor with an LED? When you talk about resistor with LED then first in your mind got Why do you need an LED resistor? Resistor…
