factors affecting self inductance of a coil when bulb connected in series

Self-inductance
If the current through a coil is altered then the flux through that coil also changes, and this will induce an e.m.f. in the coil itself. This effect is known self-induction and the property of the coil is the self-inductance (L) of the coil, usually abbreviated as the inductance.
The self inductance can be defined in two ways:

(a) Nf = LI or (b) Using the equation for the e.m.f. generated: E = - L(dI/dt)

So:The unit of inductance is the henry and it i ....etc

220v Light Bulb Dimming Circuit

INTRODUCTION

A light bulb is a device that illuminates a place. It makes light by heating a metal filament wire to a high temperature until it glows. This is done by supplying electrical current to the feed-through terminals or wires embedded in the glass.

Pulse-width modulation (PWM) is a commonly used technique for controlling power to inertial electrical devices, made practical by modern electronic power switches. It is a way of digitally encoding analog signal levels. The volt ....etc

This article is about a simple heart rate monitor using 8051 microcontroller. Like the previous 8051 projects, AT89S51 is the microcontroller used here. The device senses the heart rate from the finger tip using IR reflection method and displays it on a three digit seven segment display in beats per minute. The circuit has an accuracy of 4 beats per minute and it is very easy to use. In medical terms, the technique used here for sensing heart rate is called photoplethysmography.
