Inductors Explained - The basics how inductors work working principle

The video tutorial explains the function and importance of inductors in electrical circuits. It uses a water flow analogy to describe how inductors store and release energy, and how they behave in parallel circuits. The tutorial also covers the generation of magnetic fields by inductors, their resistance to changes in current, and how these properties are visualized using an oscilloscope. Additionally, it discusses the applications of inductors in various devices and how to measure inductance accurately.

What is the primary function of an inductor in an electrical circuit?

• To decrease the resistance of the circuit

• To store energy in its magnetic field

• To convert electrical energy into light

• To increase the voltage of the circuit

In the water flow analogy, what does the water wheel represent?

• A battery

• A resistor

• An inductor

• A capacitor

How does an inductor behave when first connected in parallel with a resistive load?

• It allows maximum current to flow through immediately

• It increases the voltage across the resistive load

• It initially resists current flow

• It immediately turns off the resistive load

What happens to the magnetic field of an inductor when the power supply is cut?

• It remains constant

• It collapses and releases stored energy

• It reverses direction

• It increases in strength

What is back EMF in the context of inductors?

• A measure of the inductor's resistance

• A type of electrical noise

• A force that opposes changes in current

• A force that assists the current flow

What unit is used to measure inductance?

• Henry

• Volt

• Ohm

• Ampere

Why is an RLC meter preferred for measuring inductance?

• It can measure voltage and current simultaneously

• It provides more accurate results

• It is easier to use

• It is cheaper than a multimeter
