Unformatted text preview: so i x = 12/5 A = 2.4 A. P4.4-9 Apply KCL at node 2: but so Next apply KCL to the supernode corresponding to the voltage source. P4.5-2 Top mesh: so R = 12 Ω . Bottom, right mesh: so v 2 = − 28 V. Bottom left mesh so v 1 = − 4 V. P4.5-6 so the simplified circuit is The mesh equations are or The power supplied by the 12 V source is . The power supplied by the 8 V source is . The power absorbed by the 30 Ω resistor is . P4.6-3 Express the current source current as a function of the mesh currents: Apply KVL to the supermesh: P4.6-5 Express the current source current in terms of the mesh currents: Supermesh: Lower, left mesh: Eliminating i 1 and i 2 from the supermesh equation: The voltage measured by the meter is:...
