In a two-source circuit, one source acting alone produces 12 mA through a given branch. The other source acting alone produces 10 mA in the opposite direction through the same branch. The actual current through the branch is

A 12 V source has an internal resistance of 90 . If a load resistance of 20  is connected to the voltage source, the load power, P_L, is

A 120 V voltage source has a source resistance, R_S, of 60 . The equivalent current source is

Determine I_N for the circuit consisting of V_S, R₁, R₂, and R₃ shown in the given circuit.

A 680  load resistor, R_L, is connected across a constant current source of 1.2 A. The internal source resistance, R_S, is 12 k. The load current, R_L, is

A certain current source has the values I_S = 4 µA and R_S = 1.2 M. The values for an equivalent voltage source are
