Inductor vs Resistor: What’s the Differences?

Inductor vs Resistor - what's the difference? If you also want to know the differences, then you are not alone. Electronic circuits often include these two components, and distinguishing between them can be tricky. To help you choose the right resistor or inductor for your next circuit, let's examine the resistor vs inductor differences!

What Is an Inductor?

By accumulating energy through a magnetic field, an inductor is an electrical device. In order for electricity to flow, it must pass through a coil or loop of wire. The electromotive force (EMF) generated by the shifting of electricity through the circuit reduces the voltage across the inductor as electricity shifts through the circuit. Using this EMF, motors or lights can be powered.

Electric inductors serve a number of purposes in a circuit, including controlling electricity flow, regulating current, isolating power sources, removing noise, and storing energy. The coils are usually tightly wound and consist of two terminals. They come in many sizes and shapes.

What Is a Resistor?

In addition to reducing current flow, resistors can adjust signal levels, divide voltages, and adjust signal levels. In this circuit, resistance is introduced (measured in ohms). During this process, energy is transformed from one form into another and the current allowed to flow through the circuit is limited. Among their many applications in electronics, resistors are often used to boost signals, reduce noise, control transistors, provide bias, and limit LED current draw.

One of the most widely used electronic resistors of its type is the MOSFET, a metal-oxide-semiconductor field resistor. The device usually has a silicon or germanium electrode sandwiched between a semiconductor material. Current is allowed or blocked by applying voltage across an electrode in a MOSFET.

Inductor vs Resistor: Best Differences

There are several types of electronic components, but inductors and resistors are the most important. Electric fields are introduced into circuits by inductors while current flows through resistors.

By responding to changing currents, inductors create magnetic fields. Circuits can be regulated by this, and energy can be stored. As opposed to resistors, inductors introduce electricity, whereas resistors resist it.

Creating resistance within an electrical circuit limits the flow of electricity through a resistor. As a result, they can prevent surges and drops in voltage within a circuit by controlling current flow.

As a result of changing currents, inductors create a magnetic field. A circuit can be controlled by controlling the flow of current or stored by using this feature. Besides storing more energy than resistors, inductors are also better suited to long-term applications than resistors.

The functions of inductors and resistors are different within circuits, therefore they are called electronic components. Unlike resistors, inductors can store energy for longer periods of time and create an electric field to control the flow of current. Having an understanding of how electronic circuits work requires an understanding of these two components.

How To Use Inductors?

There are a number of electrical circuits where inductors can be used as passive components. Electric currents and magnetic fields are converted into and out of energy by these devices. AC signals are smoothed out by filters and other frequencies are blocked by filter inductors. Transformers, rectifiers, oscillators, and voltage regulators are other circuit applications.

Electrical circuits with an inductor must consider a number of factors, including size, current rating, DC resistance, and frequency response. All these factors affect power dissipation. In order to ensure optimal performance, these variables must be selected based on the circuit application. Magnetic fields produced by other components may interact with the inductor inducing unwanted noise and interference, such as when the inductor is physically situated in the circuit.

How To Use Resistors?

The resistor is a component that is found in a large number of electronic circuits and is widely used. Electrical current is reduced or controlled, voltage drops are created, and sensitive components are protected from overcurrent damage. All resistors resist electricity flow, regardless of their shape, size, or value.

The main categories of resistors are fixed and variable. Printed circuit boards (PCBs) use fixed resistors that have a fixed value. With a potentiometer or a knob, you can adjust a variable resistor manually or electronically.

Purpose Of An Inductor and Resistor?

A magnetic field inductor stores energy by storing it in a magnetic field. It opposes the flow of current when connected to a circuit. Electromotive forces (EMF) are generated against the current flow in order to achieve this. By opposing changes in current, the EMF created by the inductor stabilizes voltage levels. Power supplies and filters, in particular, rely on them as essential components.

Resistors resist current flow when they are electrically connected. As a result, it's commonly referred to as a "current limiting device" since it limits the current in a circuit. Overloading and damaging other components can be prevented by this measure. A resistor can also act as a voltage dropper through which variable power can be controlled and signals can be isolated. Also, they help circuits work more effectively and efficiently by adjusting frequency or impedance.

Faqs

Question 1: Can we use an inductor instead of a resistor?

Answer: Due to the phase lag created when inductors are used instead of resistors, current flow through the circuit is slowed down. Current flowing through a circuit will have a 90-degree phase difference if a pure inductor is used.

Question 2: Do inductors act like capacitors?

Answer: In the real world, there are no ideal components, so an ideal inductor would not behave like a capacitor. Series resistors and parallel capacitors make up a real inductor. As a result, an ideal inductor is a real inductor.

Question 3: Do Inductors have resistance?

Answer: A coil of wire used to make an inductor has a resistance, which is what makes all inductors resistive. The Equivalent Series Resistance is also known as ESR. 

Final Verdict

Electronic components such as inductors and resistors can be classified as two types of components. A resistor resists the flow of current, while an inductor stores electrical energy. Both are useful in specific applications because they have different properties. A successful circuit design requires a thorough understanding of these components. In order to ensure a circuit operates efficiently and reliably, engineers must carefully select the right components.
