Three resistors are connected in series across a battery. The value of each resistance and its maximum power rating are as follows: 4.3? and 27.7 W, 24.6 and 8.52 W, and 14.2? and 14.3 W. (a) What is the greatest voltage that the battery can have without one of the resistors burning up? (b) How much power does the battery deliver to the circuit in (a)?
