Question

The given circuit with loop notations is shown below. Apply Kirchhoff s voltage law to loop 1, we have Apply Kirchhoff s voltage law to loop 2, we have The voltage across the 1mA current source is v2 = -7 V Substitute value of v2 from equation (2) in equation (1): we get The voltage across the 2 mA current source is V1 = 3 V The power supplied by 2 mA current source is Therefore the power supplied by 2 mA current source is The power supplied by 1mA current source is Therefore the power supplied by 1mA current source is

Explanation / Answer

In the lower current source power supply, current enters the positive terminal. For sources, if current enters into the positive terminal, the power supplied is taken Negative by convention. For current exiting from positive terminal means power supplied is positive. This is opposite for other components.
