The order of items in an AC circuit
The voltage (V) across a capacitor lags the current (I) by 90 degrees. The voltage across the inductor (L)
leads the current by 90 degrees. This is given by the word CIVIL, when split into CIV and VIL.

The different categories of radiation, in order of increasing wavelength
Cary grant expects unanimous votes in movie reviews tonight.
Cosmic, gamma, X-rays, ultraviolet, visible, infrared, microwave, radio, television.

Whether current leads voltage or lags it in reactive circuits
Think of ?Eli the Ice man?. In inductive (L) circuits, voltage (E) leads current (I), hence ELI. In capaciti
(C) circuits, it is the other way, so ICE.

The definition of mechanical adva
Men always like eating.
MA - load over effort (1/e)

The order of ohmic values in resistors
Billy brown relies on your gin but prefers good whiskey.
Black/brown/red/orange/yellow/green/blue/purple/grey/white

The additive and subtractive mixtures of colours in optics
Better get ready while, your mistress comes back.
Blue + green + red = white (additive)
Yellow + magenta + cyan = black (subtractive)

Ohm?s law
Vampires are rare.
Volts = ampere × resistance

The direction in which the current flows in a thermocouple made from antimony and bismuth metals
abc
The current flows from the antimony to the bismuth through the cold junction.

The principles of heat transfer
Conduction - Imagine a line of passengers on a bus being asked to move down by the conductor, each
passenger causing the next to bustle along (analogy for the movement/vibration of atoms that is passed
along, causing heat to be transferred).

Convection - Consider vector, a disease-carrying insect, e.g. a mosquito, which travels in swarms (very much
like the movement of convection currents).

Radiation - Heat radiation is a form of radiation - (Think of nuclear fallout or the Sun?s radiation) and thus
travels in waves undetected until they fall upon another body.

friends hope it helps u please do comment & rate on my efforts tomorrow i shall post mnemonics on chemistry

best of luck
