Verify ohm,s law |
| Answer» To verify the Ohm\'s law.Statement of Ohm\'s Law:Ohm’s law states that at a constant temperature, current \'I\' through a conductor between two points is directly proportional to the potential difference or voltage \'V\', across the two points. That is, V propto I or frac{V}{I} = constant = R or V = IRThus, the ratio V : I is a constant. This constant is called as the resistance (R) of the conductor. | |

How electricity was invented |
| Answer» Benjamin Franklin decided to do a little experiment with lightning back in 1752. He thought that lightning was interesting and wanted to find out more about it. So Mr. Franklin did something very dangerous, that none of us should try. He took a kite outside during a thunderstorm, got the string of the kite wet, put a metal key at the end and then let the kite float up into the storm. What he discovered was that the electricity from the storm clouds came down the string, and he received an electrical shock.Thomas Edison was the first recorded inventor to produce a long-lasting electric light bulb, which he created in his laboratory in 1879. He kept experimenting with improving his invention, and by the end of the 1880s Thomas Edison was able to power a few city blocks through electrical stations towards the end of the 1880s. | |

Difference between radius of curvature or principal axis |
|
Answer» Radius of curvature refers to the radius of the sphere of which mirror is a part. It usually consists the length between the pole of mirror and centre of curvature.Principal Axis refers to an imaginary straight line passing through pole, focal point and centre of curvature.Radius of a curvature is a part of Principal Axis while principal axis is a whole. 1...Radius fo curvature is distance between pole and centre of curvature while principal axis is an imaginary line joining pole focus and center of curvature of a mirror (2).....radius of curvature is of a definite measurement while principal axis is of indifinite length{however in case of numericals we never consider length of principal axis important}(3)......radius of curvature lies in front of a concave mirror and behind convex mirror while principal axis can be extended even infront and behind of mirrors(any) (4)......radius of curvature have got special sign conventions while principal axis do not (5)radius of curvature in case of convex miror is virtual while in case of concave mirror is real but principal axis is nither virtual nor real( but we take them real or virtual in some special cases) (6)......in case of convex mirror radius of curvature is positive and in concave mirror redius of curvature is negative but principal axis is never taken positive or negative(7)......radius of curvature is shorter in length as compared to principal axis------------------------The most important point------------------radius of curvature is a part of principal axis |
