rate at which the
electrons pass a section of
a wire
i = nAv
Convetional Current
The amount of charge
passing some point per
second
I= qnAv
At any node (junction) in an
electrical circuit, the sum of
currents flowing into that node
is equal to the sum of currents
flowing out of that node or
equivalently The algebraic sum
of currents in a network of
conductors meeting at a point is
zero.
The Loop Rule: The sum
of all the potential
differences around a
closed loop equals zero. Σ
ΔV = 0 for a complete loop
