Can power absorbed be negative and power supplied be positive?
When I do the calculations based on the following rule,
Current leaving the "+" side and power > 0, then power is "supplied" otherwise if power < 0 then power is "absorbed"
So 3 A leaves 15 V from the … Again with problem 1.22 but this time, it is entering + so the rule states, current entering the "+" end and power > 0, then power is "absorbed" otherwise if power < 0 then power is "supplied"
So 2 A enters …
