law of reciprocal

This law was proposed by Ritcher in 1792. It states that 'when two different elements combine separately with the same weight of a third element, the ratio of the masses in which they do so will be the same or some simple multiple of the mass ratio in which they combine with each other'...

If the resistors are connected in parallel, the reciprocal of the equivalent resistance is equal to the sum of the reciprocals of all the individual resistance..

The Properties of Complex numbers are: Commutative Law for Addition, Commutative Law for multiplication, Additive Identity Exists, Multiplicative Identity Exist, Reciprocals (Multiplicative Inverses) Exist for nonzero complex numbers, Negatives (Additive Inverses..

In H 2 S, 100-94.11 = 5.89 g of hydrogen combines with 94.11 g of sulphur. So, 1g of hydrogen combines with of sulphur. In H 2 O, 100-11.11 = 88.89 g of oxygen combines with 11.11 g of hydrogen. So, 1g of hydrogen combines with of oxygen. Ratio of the masses of sulphur (H 2 S) and oxygen (H 2 ..

Electric potential is the condition that determines direction of flow of charge. Electrical potential at a point in an electric field is defined as the amount of work done in bringing a unit positive charge from infinity to that point. Electrical potential is a scalar quantity. The potential di..

According to the principle of reversibility of light, the path of a ray of light is reversible. The figure below shows how light gets refracted from medium 1 to medium ..

Incident Ray The ray of light striking the surface of separation of the media through which it is travelling is known as the incident ray. Point of Incidence The point at which the incident ray strikes the surface of separation is called the point of incidence. Normal The perpendicular ..

. It is measured in lumen /watt. Laws of photometry state that E a I; E a cos q , where q is the angle, which the incident light makes with normal to the surface at that point. Or A photometer is an instrument, which is used for comparing the illuminating powers of two sources of light. W..
