linear relation of v and i

The constant a , which describes the thermal expansion properties of a particular material, is the coefficient of linear expansion. The units of a are K - 1 or (C O ) - 1 (remember that a temperature interval is same in both the Kelvin and Celsius scales). For many materials, linearh..

Comparison of Linear and Rotational Motion - When a rigid body such as a merry-go-round rotates around an axis, each particle in the body moves in its own circle around that axis. Since the body is rigid, all particles make one revolution in the same amount of time. i.e., they all have th..

Different forms of numbers Scientific notation, square roots, exponents, radicals, absolute value, factorial, logarithms Properties of numbers Estimation of solutions Sequences and series Proportionality/direct variation, exponential/fractional expressions Patterns, relations and ..

(a) The terminal voltage V (the voltage drop across the terminals of the battery) is related to the EMF of the battery (open circuit voltage drop) by the relation, V = E - Ir Now, E = 12 V, I = 90 A or V = 12 - 4.5 = 7...

It is prepared by heating white phosphorus to about 540 K in an inert atmosphere of nitrogen for several hours...

Ohm's Law - It is found experimentally that the current I flowing through a conductor is directly proportional to the potential difference V across its ends, provided the physical conditions (temperature, mechanical strain, etc.,) remain constant. That ..

Limitations of Ohm's Law - Ohm's law is not a fundamental law of nature. There are a number of commonly used circuit elements which do not obey this law. They have one or more of the following properties: 1. V depends on I non-linearly. 2. The relationship between V an..

1) Both magnetic and electric field depend inversely on the distance between the source and the field point 2) Both are long-range forces 3) Principle of superposition applies to both fields as the fields are linearly related to the source..
