\$\begingroup\$

if the question lies "Which unit uses the most power? How much power does that unit use?"

Does that mean how much power is dissipated through heat or is it about the voltage/current sources they are talking about?

Use this circuit as visualization. enter image description here

    \$\begingroup\$ "Unit" is not a standard name for anything. It could be an individual component, a source, or the whole circuit. You need to read your book. \$\endgroup\$ – pipe Oct 15 at 7:41

    \$\begingroup\$ It's a bit vague. The term "uses" suggests "consumes" and that suggests the resistors but the current and voltage sources consume power from somewhere as well. I agree with @pipe that context from the course should clarify this. \$\endgroup\$ – Transistor Oct 15 at 7:48

    \$\begingroup\$ @pipe and Transistor I do agree with you guys. This was an old exam question that I'm trying to understand without confusing myself. When I measured each component, R1 used 55mW, which was the most power used. However, I wanted to ask people here if they could possibly clearify. \$\endgroup\$ – gripen Oct 15 at 8:10

    \$\begingroup\$ I think the use of the word "unit" is OK. In this context, "unit" unambiguously means "component", "device". \$\endgroup\$ – tlfong01 Oct 15 at 9:15

    \$\begingroup\$ To answer a bad question : 1) make an assumption. 2) Clearly state that assumption in your answer, and your reason for making it. 3) Answer the question according to that assumption. If you have time left over, explore a different assumption. (For what it's worth, I think your assumption was reasonable) \$\endgroup\$ – Brian Drummond Oct 15 at 9:34
