All capacitors store charge.If we connect a resistance in series with the capacitor, then it will take some fininte time to get fully chaged.Time constant is the time required to charge the capacitor, through the resistor, by ≈ 63.2 percent of the final value. It can be mathematically denoted as the product of R and C. Here in this this circuit as we turn on the power and move the s2 towards v2, the cpacitor gets charged upto v(applied voltage), as we move the s2 towards v3, the capacitor starts discharging and led starts glowing. By observing the led we can get the idea of time constant of the capacitor.

Pedal Powered Electricity Generation
The main objective of this project is to utilize the human power to produce electrical energy. The basic principle of this project is to convert Human Mechanical Energy into Electrical Energy using a DC Generator. The Input Low Speed- High Torque Human Powered Pedal Energy is transmitted as well as converted into an Output High Speed Rotary Motion of the DC Generator in order to produce Electricity. For power transmission purpose, a Chain- Sprocket assembly as well as a Belt – Pulley Drive is used to efficiently transmit power, speed and torque throughout the system.
The system consists of a Bicycle, Dynamo, Belt drive and other support accessories to demonstrate the application.

Mechanical Projects, School & Engineering ProjectsAutomatic street light controller with road power generation
We have used a sensor called LDR which has the property to change its resistance according to the intensity of the light. As the intensity of light falling at the LDR increases, its resistance gets decreased and vice versa. Hence the total intensity of light remains constant.
It is one of the most recent power generation concepts. This device is engineered as a practical and useful alternative energy technology for generating clean electricity from the millions of vehicles on our roadways and utilizes this electrical energy efficiently when required.

High Pass Filter using RC Circuit
Filter circuits are used to filter the undesired frequency components of the signal. High pass filter allows the high frequency component while attenuates the low frequency components. Here we are having two different types of signals one is from dc and other is from ac.
