Homologous Series
Homologous Series - All organic compounds are made up of a progressively building chain of carbon atoms with a number of compounds having the same functional groups. Such a series of similarly constituted compounds are called a homologous series. Members of a homologou..
Electrochemical Series
Electrochemical Series - Different electrodes have different standard electrode potentials. The standard electrode potentials (E) for some electrodes are negative, while for some others E values are positive. The E values of many electrodes have been measured and their..

Resistances in Series
If the resistances are connected end-to-end, the same current flows through each resistance, as there is no alternative path. Then where I is the current, V is the potential difference of the battery and R S is the equivalent resistance of the combination. Now, V = V 1 +V 2 +V 3 ..

Resistors in Series and in Parallel - When resistors, can be connected in such a way that the same current flows in them, then they are said to be connected in series. The resistors are said to be connected in parallel if the potential difference is the same across eac..
Combination of Resistances in Series and Parallel
Resistors can be combined in different ways. When two or more resistors are connected end to end, so that the same current flows through all of them then, the resistors are said to be in series..
Combination of Resistors in Series and Parallel
Resistors can be combined in different ways. When two or more resistors are connected end to end consecutively, so that the same current flows through all of them then, the resistors are said to be in series..
Law of Combination of Resistors in Series
The equivalent resistance is the sum of the individual resistances connected in series. The above result can be generalised for 'n' number of resistances of different values as R = R1+ R2 +............ + R..
Electrochemical Series of Metals
Different metals get ionised at different rates. For e.g., metals like sodium when exposed to air combine almost instantly with the oxygen present therein (sodium atom gives up an electron almost as soon as it is in contact with oxygen). On the other hand, metals like gold if ex..

this tutoring is EXCELLENT! :) they were very clear on expliaing things and i was able to grasp thing very quickly - Stephanie
I need tutoring from tutorvista till th end of my schooling. Tutors are not only experts they are brilliant enough to make a student like me understand the concepts of differentiation and functions.
My grades increased drastically with Tutor Vista and I'll definitely recommend this to all students who want to do better in their school. Not only do we learn, we also have fun!
Hi, I am Ethan, I am in Grade 11. I subscibe to TutorVista tutoring few weeks back and I am liking it.
