EEE Interview Questions-1

Here are some of the basic questions asked in interviews for EEE students 1. what is the principle of motor? The electric motor is based on the principle that whenever a current carrying conductor is placed in an magnetic field it experiences a mechanical force i.e turning or twisting movement is called as torque. 2. what is the principle of generator? The electric generator is based on the principle of faraday's law of electromagnetic induction. Such that whenever a current carrying conductor is placed in an varying magnetic field it induces an emf in it. 3. what are the types of DC motor? Series motor Shunt motor Compound motor Permanent magnet DC motor 4. What are the types of AC motor? Synchronous motor Asynchronous motor 5. What is Synchronous motor? Synchronous motor is a kind of AC motor where the rotation of the shaft is synchronized with the frequency of the supply current at steady ...

Resistor - Basic Electrical Component I

Definition: It is a two terminal passive electrical Component that resists the flow of current in circuit Resistor How it Works: It converts electrical energy into heart which will dissipated into Air Uses of Resistor: Reduce Current Flow Adjust Signal levels Divide Voltage Bias Active Element Unit of Measurement: Unit of Resistor is Ohm which is name after the scientist George Simon Ohm Types of Resistor: There are two main types of Resistor: Linear Resistor Non-Linear Resistor Linear Resistor: Linear Resistor is a resistor those Value changes with change in temperature and current Types of Linear Resistor: Fixed Resistor Variable Resistor Fixed Resistor: In this the Value of Resistor is fixed it doesnot change with changes with temperature and Current Types of Fixed Resistor: Carbon Film Resistor Wire wound Resistor Thin Film Resist...
