What is an Inductor? Simple Guide
An inductor is an electronic component that stores energy in the form of a magnetic field and opposes sudden changes in current.

What is a Capacitor in Electronics? Simple Explanation
A capacitor is a two-terminal electronic component that stores electrical charge for a short time. It has two metal plates placed close to each other.
What is Voltage and Current?
Voltage is the potential difference between two points in a circuit. Current is the rate at which electric charge flows through a conductor or circuit.
What is Leakage Current?
Leakage current is the small amount of current that flows through an unwanted path, even when an electrical device is switched off or properly insulated.
What is Resistor?
The resistor is a passive electrical component that creates resistance in the flow of electric
current. It is measured in Ohms(Ω) and denoted by ‘R’.
Electrical Active and Passive Components
An active component in a circuit is a part that needs power to work. A passive component is a part that doesn’t need power to work.
