model‚ use computer aided design software to analyze the circuit performance and demonstrate the working of the circuit by hardware implementation. Then‚ we will plot the frequency response of the circuit and analyze the effect of the emitter bypass capacitor. Finally we will compare the mid-band gain‚ bandwidth and lower cutoff frequency obtained from the simulation result and the hardware implementation with the designed values.

a compact form of memory that is often inexpensive. The DRAM stores each and every bit of data in separate capacitor that are found within an integrated circuit. There can be discharging or charging of the capacitor; these two states can therefore be taken as a representation of two values of a bit that are conventionally known as 0 and 1.there should be periodic refreshing of the capacitor since it leaks charge least the information stored there eventually fades away this is hence why it is known

Electrical Machines - Questions and Answers Information courtesy of ALSTOM. INDUCTION MOTOR CONTROL GEAR 1. What are the main functions of control gear? 1. To provide a means of starting and stopping the motor and‚ at the same time‚ of limiting the starting current if required. 2. To give adequate protection to the motor under all conditions. 3. To allow speed changing when required. 4. To provide means of braking the motor when required. 5. To reverse the direction of rotation

INTRODUCTION Wouldn’t it be nice to have your home take care of your thing for you‚ automatically‚ without you having to lift a finger? You bet it would. This is the promise of Home Automation. There are many different systems‚ especially in larger homes‚ that can benefit from being integrated. Some of these systems include security alarm‚ HVAC‚ audio/video & lighting. Home automation integrates together‚ enabling them to function more efficiently‚ improve functionality‚ conserve resources & enhance

protecting the parallel port from overloading. Firstly the power supply is built‚ a 240v-15v AC transformer is used‚ the 15v section of the transformer is solder to the vero board and a bridge rectifier is fixed to the wires on the board‚ the filtering capacitor (1000uf) is connected to DC output of the rectifier‚ then a voltage regulator (LM7812) is connected to the output of the rectifier‚ this steps completes the power supply so the parallel port cable is soldered to the board and the opto-isolator are

In Unit 5 Activity 2 we were asked to predict and then find the brightness and flow rate of a closed circuit with a three cell battery pack‚ a long bulb‚ a capacitor parallel to the long bulb‚ and a round bulb. I originally predicted that the round bulb would be brighter when the circuit was first closed and when the circuit reached a steady state‚ and that the wire between the round bulb and the negative side of the battery would have a higher flow rate than the other wires. However‚ in the steady
