Hey guys,
So the sign convention for power is really confusing me. According to my knowledge, if a positive current is entering the positive terminal of an element, the voltage drops across the element and power is hence absorbed. Why does the question solution change the sign of the current and say that the power is negative though? I am really confused =[
Help me please!
Thanks!
