Project Motivation: Karachi Electric Supply Company is the sole electric power supplier in Karachi city. Though it enjoys the monopoly in the town‚ but for past 10 years‚ it has been facing serious issues in generating and distributing the demanded power supplies to the City. The motivation as business students to pursue the project for the improvement in current KESC conditions is driven from the fact that prevailing problems at Karachi Electric Supply Company is badly affecting the industries

SOLUTION TO CASE STUDY – HARSHA AT SIRSA Summary of Case The various units of Banarsi Das are scattered. Unit I is located near the grain store having Flour mill and standby power supply. Unit II is behind the railway station having Flour mill and maintenance workshop and Unit III is next to the bus stand having Bakery and Finished Goods Store. The above mentioned all sites are at some distance from one another and there is no scope for any expansion at any of the sites. Banarsi Das’s daughter Harsha

The transistor will be OFF and nothing happens. When there is sufficient smoke to mask the light from falling on LDR‚ the LDR resistance increases and so do the voltage across it. Now the transistor will switch to ON. This gives power to the IC1 and it outputs 5V. This powers the tone generator IC UM66 (IC2) to play a music. This music will be amplified by IC3 (TDA 2002) to drive the speaker. Resistor R6 is meant for protecting the transistor when R4 is turned towards low resistance values. Resistor

Abstract: The main aim of this assignment is to design a pre amplifier circuit with an NPN transistor to be used in a simple public address (PA) system. The pre amplifier is fed from a microphone that produces an average output voltage of 10 mV rms. The amplifier is to operate over a frequency range of 300 Hz to 5 kHz and should have an adjustable volume control. The expected gain of the amplifier is 100. First we are going to design an amplifier for given specifications‚ model the operation of the

recharged or replaced periodically. It is a hassle to charge or change the battery after a while‚ especially when there is no power outlet around. Therefore‚ our team is inspired to design a wireless battery charger. This wireless battery charger is expected to eliminate all the hassles with today’s battery technology. Wireless power is the transmission of electrical energy from a power source to an electrical load without a conductive physical connection. Wireless transmission is useful in cases where

METER” prepared by us can be used to find out how much electricity appliances in our house are using and how much they cost to run. INTRODUCTION If we want to save power and reduce costs‚ we need to know how much power each appliance uses over a period of time. Most appliances don’t run all the time‚ so we need to know the power they use while

The devices connected as home and office appliances consume electrical power and they should be controlled as well as turn on /off if required. Most of the time‚ it was done manually. Now it is a necessity to control devices more effectively and efficiently at anytime from anywhere. Take an instant when we are going to office
