The maximum number of volts, E, that can be placed across a resistor is given by the formula E=sq root(PR), where P is the number of watts of piwer that the resistor can absorb and R is the resistance of the resistor in ohms. Solve this equation for R. Use the result to determine the resistance of a resistor if P is 1/2 watts and E is 60 volts.
