Abstract

Voltmeter is a measuring instrument, used to measure the voltage difference between two points in electrical network. Generally there are two types of voltmeters one is analog voltmeter and the other one is digital voltmeter. In analog voltmeter a pointer moves on the scale to represent the voltage. Digital voltmeter directly displays the voltage in digits with the help of analog to digital converter. This article explains you how to design a digital voltmeter in two methods 1) using 8051 microcontroller and 2)the other using IC L701 ....etc

hopkinson test wikipedia

Hopkinson's test is another useful method of testing the efficiency of a dc machine. It is a full load test and it requires two identical machines which are coupled to each other. One of these two machines is operated as a generator to supply the mechanical power to the motor and the other is operated as a motor to drive the generator. For this process of back to back driving the motor and the generator, Hopkinson's test is also called back-to-back test or regenerative test.

If there are no losses in the machine, then ....etc

ABSTRACT
Our mini project was inductance meter using 89c2051 microcontroller. As an expansion and knowledge improvement we have opted for LCF meter as our final year project. Which is not only challenging but also useful device. To be different our choice was LCF meter (inductance , capacitance and ....etc

Materials Required: A Resistance wire, voltmeter, ammeter, battery, rheostat, meter scale, one way key, connecting wires etc.

Theory: If I be the current flowing through a conductor & V be the potential difference across its ends, then according to Ohm s law
V I
or V = RI
Where, R is the constant of proportionality. It is known as resistance of the conductor.
V/I=R
R depends upon the nature of material, temperature & dimensions of the conductor.
