It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = πr2h and τ = rF sinθ. When a variable with an exponent or in a function is covered, the corresponding inverse is applied to the remainder, i.e. and Image mnemonics in the style of the Ohm's law formula triangle for high-school physics – in the SVG file, hover over a symbol for its meaning and formula
Once upon a time, the symbol E (for electromotive force) was used to designate voltages. Then, every student learned the phrase
ELI the ICE man
as a reminder that:
For an inductive (L) circuit, the EMF (E) is ahead of the current (I)
While for a capactive circuit (C), the current (I) is ahead of the EMF (E).
The phrase "We guarantee certainty, clearly referring to this light mnemonic." represents the speed of light in meters per second through the number of letters in each word: 299,792,458.[4]
