for the second, V = I*R
R increases, V increases
thats wat i can think of now.

ya how B ? y- axis thts y??
but when R increases, doesnt the value of the current in the circuit in the change ??

also can it be used to measure a pipe?

Hmmm... Vernier calipers can measure internal dimensions (using the uppermost jaws in the picture given), external dimensions using the pictured lower jaws, depth measurements by the use of a probe that is attached to the movable head and slides along the centre of the body. This probe is slender and can get into deep grooves that may prove difficult for other measuring tools.
The vernier scales may include both metric and inch measurements on the upper and lower part of the scale.
Vernier calipers commonly used in industry provide a precision to a hundredth of a millimetre (10 micrometres), or one thousandth of an inch.
A more precise instrument used for the same purpose is the micrometer. I hope this info helps googled it.. ;) check the picture attached..

Is any1 free enough to post for me the electromagnetic spectrum in order of frequency and wavelenth .
I know that one goes opposite to the other .
Plus,an explanation of total internal reflection is helpful too.
Thanks in advance.
rhea:
whats the use of a
split ring commutator
slip ring commutator?
IN DETAIL please?

Nah, i dont think it changes..the share of the voltage received decreases.
and abt that. The time base is the x-axis. The a/c current produces the y-axis.
-------- |
| <- only a.c current
only time base |

when they combine they form the wave.
