Homework Statement



Two resistors, R1 and R2, are connected in series across a potential difference, ΔV0. Express the potential drop across each resistor individually, in terms of these quantities.

The Attempt at a Solution


R1 + R2 = Req
I = V0 / Req

drop at
V1 = V0 / (req) * R1
V2 = V0 / (req) * R2

i think this right?

That should be correct assuming you mean that V1= (R1/Req)V0 and similar with V2.

This sort of circuit set up is also referred to as a potential divider or voltage divider.
