MATLAB SIMULATION OF SERIES RC CIRCUIT This will be divided into: Practical analysis Theoretical analysis Conclusion Circuit diagram of RC circuit Using the RC branch, with R = 1Ω and C=1000uF MATLAB SIMULATION WAVE FORMS Scope 2 Input voltage Current flowing in the circuit Voltage drop across the capacitor   Observing the wave form from scope2, we can see that the wave form of the current leads the wave form of the voltage by 90 0 . This is in line with the fact that  in pure capacitive circuit the current leads the voltage by an angle of 90 o and in a non-pure capacitive circuit by an angle < 90 0 . Scope 3 Voltage drop across the capacitor Voltage drop across the resistor   From scope3, we observe that the voltage across the capacitor (V C ) , is out of phase with the voltage across the resistor (V R ) by 90 0 . Where V C lags V R with V R and I in phase. THEORITICAL ANALYSI S Using the RC branch,...

GENERATION OF ELECTRICAL ENERGY FROM BIOMASS 1.1. INTRODUCTION Energy is the most vital issue for all living-being on earth. Modern life style has further increased its importance since a faster life means a faster transport, faster communication, faster manufacturing processes etc. All these lead to an increase in energy required for all these modern systems. These energy come from different sources and one of these sources is the biomass or biofuel energy production (generation) source. 1.2. DEFINITION OF BIOMASS Biomass or Biofuel is a fuel that is developed from organic materials, renewable and sustainable source of energy used to generate electricity or other forms of energy. It is the organic material that is used for the production of energy known as biomass . 1.3. DESCRIPTION  OF BIOMASS The biomass plant is a renewable source of energy because wastes residues will always exist be it in terms of scrap wood, forest resources, manure etc...Developing ...

Interfacing a 16X4 LCD In this project, a 16X2 LCD is connected to PORTB of PIC 16F877A microcontroller and the microcontroller is operated from an 8MHz oscillator. The message to be displayed is "welcome to 16x2 LCD display". A reset button is include to be able to reset the microcontroller.

Differences between MCB and MCCB, and characteristics The first thing here is to know the meaning of the abbreviations MCB and MCCB. What does MCB and MCCB stand for? MCB stands for Miniature Circuit Breaker. MCCB stands for Molded Case Circuit Breaker Miniature Circuit Breaker (MCB) It is an electromechanical device used to protect a low load electrical circuit. It is thermally operated and used for protection against over load, heating and short circuits, in circuits requiring a small current rating (less than 100A). It is designed to replace the ancient fuse rewirable device. The Miniature circuit breaker (MCB) functions as an automatic switch OFF device which routinely turns OFF when the current flowing through it passes the threshold (maximum acceptable limit). This is achieved through the use of a bimetallic strip which protects against overload and the use of a solenoid which protects against short circuit. Application of MCB : low load domestic and in...
