Solve the problem.The maximum number of volts, E, that can be placed across a resistor is given by the formula 
where P is the number of watts of power 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 
watts and E is 30 volts.
A. R = 
; 3,600 ohms
B. R = E2P2; 14,400 ohms
C. R = 
; 14,400 ohms
D. R = E2P; 3,600 ohms
