Homework Help: Maximum voltage

  1. Apr 6, 2008 #1
    1. The problem statement, all variables and given/known data
    Three 100 resistors are connected as shown in the figure. The maximum power that can safely be delivered to any one resistor is 28.0 W.

    2. Relevant equations
    P = VI

    3. The attempt at a solution
    I found the total resistance of the circuit, but i dont know how to get the current, which i need for the voltage

    The maximum current flows through the resistor on the left. So, if you calculate that current (from the power), you can get the voltage by using Ohm's law.

    I'm not sure if this is correct.

    Could you be a little more clear about what you want to solve? For example do you want voltage across any particular resistor or voltage between A and B?

    never mind ....i found the answer. What i wanted was the maximum voltage to each resistor.
