Homework Statement
three resistors R1=R2 and R2=2R3, are connected to a battery, as show in the figure, if the power dissipated for each one is p1,p2 and p3 respectirvely;p3 must be equal to:
Homework Equations
P=VI
P=V^2/R
P=I^2*R
The Attempt at a Solution
I have tried to find the total resistance in the circuit by knowing that R2 and R3 are in parallalel and this equivalent resistance let's call it R23 will be in series with R1 so the equivalent resistance would be Req=R1+R23 this will allow me to find the total current in the circuit which is I=V/Req while doing so I should be able to find the power in R1 with this P=I^2*R1 since the total current in the circuit is the same going through R1, but I can't find the relationship with the power dissipated with P2 and as you can see P1 is in terms of P2
