E1=120V; E2=60V; R1=R2=R3=R=30ohm

a)Find the value of Rsh, for maximum power on that resistor.
b)Find that power.

So...Rsh should equal to Rth (Thevenin)
a) Rth=R1+R1||R2||R3=30+10=40ohm
b) Eth=20V
I=0.25A
P=I^2*Rsh=2.5W

Am I right ?

 

Anyone...PLEASE

BUMP

 

Yes, your answer looks good.
Are you happy now ?

 

yeah, I wasn't sure about Eth
