Producing Electricity from Potatoes (PROJECT)

Image
Producing Electricity from Potatoes (PROJECT) A primary voltaic cell makes use of a dilute solution of sulphuric acid in which one plate each of copper and zinc is dipped. The electricity in this cell is produced due to the migration of electrons from the zinc plate to copper plate in the dilute sulphuric acid solution. In fact, dilute sulphuric acid provides the path for the movement of electrons. in a similar way, potatoes act like the solution of dilute sulphuric acid between the copper and zinc strips which are used for producing electricity from potatoes.

what is Attenuator? (NFTL)

Image
Attenuator :-       An attenuator is normally a four terminal network inserted between a source and load. It is introduced to incur a specific amount of loss for current and voltages. In order to prevent attenuation distortion, all source frequencies must be attenuated to the same degree and thus the network generally consists of purely resistive components.   Where,                 = source voltage (V)                 = load voltage (V)                 = source current (A)                  = load current (A)                 = power input (WATT)                 = power output (WATT)                 = input impedance (Ω)               ...

The contribution of Industry to National Economy : (a) Manufacturing sector has stagnated at 17 per cent of GDP for the last 2 decades (b) East Asian economies 25 to 35 per cent (c) The National Manufact...

What Is FLIP-FLOPS ? Full Explain With Diagram

FLIP-FLOPS AND OTHER RELATED DEVICES SEQUENTIAL CIRCUITS sequential circuits The digital circuits discussed so far have been combinational i.6., the outputs at any instant of time are entirely dependent upon the inputs present at that time. Most of the digital systems used in practice do not have only combinational circuits but also include memory elements. Thus the sequential circuits are made up of combinational circuits and memory elements . Fonts For Facebook   Generate cool and stylish   fancy fonts for your Facebook account and  Facebook Fonts   you can use in all social media platform  Fonts For FB A block diagram of a sequential circuit is shown in Fig. 6.1. It consists of a combinational Circuit to which memory elements are connected to form a feedback path. The memory elements are devices capable of storing information. The information stored in the memory element at any given time defines the state of the sequential circuit. ...

What Is Databases?

Databases INTRODUCTION: A database system is basically a computer based record keeping system. The collection of data, usually referred to as the database, contains information about one particular enterprise.  Fonts For Facebook   Generate cool and stylish   fancy fonts for your Facebook account and  Facebook Fonts   you can use in all social media platform  Fonts For FB It maintains any information that may be necessary to the decision-making processes involved in the management of that organization.  The intention of a database is that the same collection of data should serve as many applications as possible. Hence, a database is often conceived of as the repository of information needed for running certain functions in a corporation or organization. Such a  database would permit not only the retrieval of data but also the continuous modification of data needed for control of operations.  This chapter is goin...
