Potential drop across each resistor

Click For Summary
SUMMARY

In a series circuit with two resistors, R1 and R2, the potential drop across each resistor can be calculated using the formula V1 = (R1 / Req) * ΔV0 and V2 = (R2 / Req) * ΔV0, where Req is the equivalent resistance given by Req = R1 + R2. The current I through the circuit is determined by I = ΔV0 / Req. This configuration is commonly known as a voltage divider.

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.
