## Difference between Brushed and Brushless Motors

Brushless DC motors are the one which use an electronic commutation and are powered through a DC source using switching supply and an inverter, which basically generates an AC electrical signal for driving the motor in order to drive the motor. Performance is the main concern for such motors and …

## Difference between Capacitor and Battery

Capacitor and battery both perform the same function of storing and releasing an energy, however, there are essential differences between both of them due to how they function differently. Capacitors store energy in the form of an electric field while batteries store energy in the form of chemical energy. The …

## Linearity in Circuits

Consider the relationship between voltage and current for a resistor (Ohm’s Law). Suppose that c current I1 (the excitation or input) is applied to a resistor, R. then the resulting voltage V1 (the response or output) is ${{V}_{1}}={{I}_{1}}R$ Similarly, if I2 is applied to R, then V2=I2R results. But if …

## Difference between AC Drives and DC Drives

The AC drives operate with AC signal or voltage, for instance, 1-phase or 3-phase AC voltages whereas DC drives operate with DC signal or voltage, for instance, DC supplies, and Batteries. Generally, a DC drive changes an Alternating Current (AC) into Direct Current (DC) using a converter (Rectifier) to operate …

## Difference between Autotransformer and Conventional Transformer

In two winding transformer, whole power is transferred from primary to secondary side by means of induction ONLY While, in the case of Auto transformer, part of the whole power is transferred by induction and rest of the power is transferred through conduction. In two-winding transformers, primary and secondary windings …

## Difference between Analog and Digital Signal in Tabular Form

Analog signals and Digital signals are the two categories of signals. These signals are utilized in order to broadcast different types of information. Analog signals are the ones that observe analog methodology to broadcast information in such a fashion that they can be analyzed at any instant of time while Digital …

## Difference between Analog and Digital Multimeter

A multimeter is a device which is used to measure several electrical quantities such as current, voltage, resistance, inductance, capacitance, and electrical frequency. The most significant difference between an analog multimeter and the digital multimeter is that the analog multimeter comprises of a scale and a deflection pointer which actually …

## Ammeter vs Voltmeter | Difference between Ammeter and Voltmeter

Devices like ammeter and voltmeter are employed in order to measure electricity. Both of these devices are based on the galvanometer which is employed to detect small current. An ammeter is a device which is used to measure the “current” (in ampere, micro-ampere, and milli-ampere) through a conductor whereas a …

## Difference Between Active and Passive Components

Active Components Electrical Components which need an external source to initiate the operation are known as active components such as Silicon-Controlled Rectifier (SCR), Transistors, and Diodes. Example Since a Diode is an active element so it needs an external source (either voltage or current) in order to initiate the operation. …

## Difference between AC and DC Power

AC power alters its direction with time, while DC power remains constant. Furthermore, AC power oscillates at 60 Hz frequency whereas DC power has Zero frequency. The main advantage of an AC power over DC is that it can be transmitted over long distances at higher voltages using transformers with …

## Difference between AC and DC Motor

An electric motor is a machine that converts electric energy into mechanical energy. An electrical signal (voltage) is applied to the input terminals of the motor, and the output of the motor output generates a specific torque according to the motor characteristics. AC motors and DC motors perform the same …

## Difference between AC and DC Generator

The AC generator generates an output voltage which alters in amplitude as well as time whereas the DC generator generates a constant output voltage which does not change in amplitude as well as time. The electrical energy we utilize has two fundamental types, one is known as Alternating while the …

## Difference between AC and DC Current

Electrical current flows using two ways: either in a direct current or in an alternating current (AC). Electric current is basically the free movement of electrons by a conductor. The main difference between AC and DC is based upon the direction in which the flow of electrons occurs. DC Current …
