What is a Resistor? An electric resistor is a two-terminal passive component specifically used to oppose and limit current. A resistor works on the principle of Ohm’s Law which states that voltage across the terminals of a resistor is directly proportional to the current flowing through it. Ohm’s‚Law: v=IR where V is the voltage applied across resistor‚ I is the current flowing through it‚ and R is the constant called resistance. The unit of resistance is ohms.

EE 2403 SPECIAL ELECTRICAL MACHINES 2 MARKS UNIT-I - SYNCHRONOUS RELUCTANCE MOTOR 1. What is synchronous reluctance motor? A reluctance motor is a type of synchronous electric motor which induces non-permanent magnetic poles on the ferromagnetic rotor. Torque is generated through the phenomenon of magnetic reluctance. 2. Define the characteristics of synchronous reluctance motor. The synchronous reluctance motor is not self starting without the squirrel cage. During run up it behaves as an induction

Marie Curie (French: [maʁikyʁi]; 7 November 1867 – 4 July 1934)‚ née Maria SalomeaSkłodowska (Polish: [ˈmarjasalɔˈmɛaskwɔˈdɔfska])‚ was a Polish physicist and chemist‚ working mainly in France‚[2] who is famous for her pioneering research on radioactivity. She was the first woman to win a Nobel Prize‚ the only woman to win in two fields‚ and the only person to win in multiple sciences. She was also the first female professor at theUniversity of Paris (La Sorbonne)‚ and in 1995 became the first woman

AUTO MUTE FOR AUDIO DECK (Automatically Mute Your Audio System when you receive a call) Muting car’s audio deck‚ while talking on cell phone is an important yet difficult task. This project is designed to solve the problem. A sensitive IR transmitter and receiver pair is designed and fixed to a cell phone holder. Always the cell phone should be placed in the holder. The transmitter unit continuously transmits IR rays. These IR rays are interrupted by the cell phone. Whenever the cell phone

CHAPTER 4 AIRCRAFT BASIC CONSTRUCTION INTRODUCTION Naval aircraft are built to meet certain specified requirements. These requirements must be selected so they can be built into one aircraft. It is not possible for one aircraft to possess all characteristics; just as it isn’t possible for an aircraft to have the comfort of a passenger transport and the maneuverability of a fighter. The type and class of the aircraft determine how strong it must be built. A Navy fighter must be fast‚ maneuverable

ELECTROMAGNETIC BRAKING SYSTEM A PROJECT REPORT Abstract The Project is based on one of the modern braking technologies‚ with the introduction of ABS (Anti-lock Braking System)‚ Brake-by-wire technology‚ electronic brake force distribution (EBD)‚ traction control system‚ emergency brake assist‚ or electronic stability control (ESC). The braking technology has reached a new peak. In this project electricity is applied to the coil at the time of braking. This develops a magnetic field around it and

REMOTE CONTROLLING OF HOME APPLIANCES ABSTRACT The main aim of conducting this project is to control a maximum of eight electrical appliances by just using a TV remote. Normal IR circuits can switch only one device. But using this circuit‚ different devices can be controlled using same remote with different switches. In this circuit‚ we interfaced 8 devices. These devices are switched using remote keypad -1 to 8. AT89C51 microcontroller is used to control the inputs and
