Starting electronics
Thus, a current of, say, 1 A flowing through a resistance of
5 Ω, produces a voltage of:
across the resistance.
These three expressions which combine to make Ohm’s law
are the most common ones you’ll ever meet in electronics,
so look at ’em, read ’em, use ’em, learn ’em, inwardly digest
’em — just don’t forget ’em. Right? Right.
Take note — Take note — Take note — Take note
And another thing. See the way we’ve said throughout,
that a voltage is applied or produced across
a resistance. Similarly a current flows through a
resistance. Well let’s keep it like that! Huh? Just
remember that a voltage is across: a voltage does not
flow through. Likewise, a current flows through: it
is not across.
There is no such thing as a flow of voltage through a
resistance, and there’s no such thing as a current
across a resistance.
