what is potential difference
the energy transfered per coulombe of charge
what happens to pd in a series circuit
the supply is shared between components
V1 = V2 + V3
what happens when components are identical
they get an equal share of the pd
what happens to current in a series circuit
the current is the same at all points
if we add more components in a series we increase what
the total resistance
the total resistance is the sum of…
..the individual resitances
