An alternating current is another type of electric current whose magnitude changes continuously with time and direction changes periodically. Due to technical and economic reasons, we produce alternating currents that have sine waveform (or cosine waveform) as shown in the figure. Alternating AC Curren...
An electric current is the flow of electric charge through a conductor. Based on the flow of electrons constituting the current, electric current is classified into two types, direct current and alternating current.Direct Current (DC) Direct current abbreviated as DC or dc, is an electric ...
Electric Motor Definition: An electric motor is a device that converts electrical energy into mechanical energy using magnetic fields and electric currents. Core Functioning: The main principle behind all electric motors is Faraday’s Law of induction, which describes how a force is generated from ...
Note:Electric current is ascalar quantityeven though it has magnitude and direction because it does not obey vector laws. So simple laws of algebra are used to find net electric current. Types of Electric Current Electric Currents or simply current can be classified as 1. Direct or steady curr...

In all transformers except auto-transformers electric power is transferred from one circuit to another by a common magnetic field produced. When an alternating current is applied to the input side of the transformer, it produces a magnetic field. Due to the sinusoidal nature of the AC supply, ...
What are the types of electric motors? Electric motors are divided into three broad categories, namely, AC motors, DC motors, and special motors. AC motors use alternating currents and convert them into mechanical energy. It is further classified into synchronous and asynchronous motors. DC motors...
AC Defibrillator Definition: An AC defibrillator is defined as the oldest and simplest type of defibrillator that uses a 50 Hz AC shock to resynchronize the heart. Countershock: Countershock is the procedure of applying an electric shock to the chest to restart the heart. DC Defibrillator Defini...
