Homework Statement
Three 100ohm resistors are connected as shown. The maximum power that can safely be dissipated in any one resistor is 25W
What is the maximum potential differencethat can be applied between points A and B.
Homework Equations
Ohms Law, V=IR
P=V^2/R
The Attempt at a Solution
I simplified the circuit down until I had one single resistor of 150ohm then used P=V^2/R, so 25= V^2/150, rearranged and got V=61V however this is incorrect.
