Assume that you are adding two 4-bit numbers. What does a carry-out (in the fifth place) indicate. Does this carry-out indicate something different when we add two positive numbers, a positive and negative number, or two negative numbers.
A 120V source is connected in parallel with four (4) resistors, all of which are in parallel. The resistors have the ratios 1 : 2 : 3 : 6 (for example 4Ω, 8Ω, 12Ω, 24Ω). The source delivers 288W to the parallel combination.
