Unformatted text preview: Exam 2 Practice Problems For Problems 1-21, use the figures at the end of this document. 1. Calculate the power dissipated by each resistor in Figure 1. Resistor Power 2 Ω 2.40W 10 Ω 0.100W 5 Ω 5.00W 8 Ω 6.50W 3 Ω 1.30W 2. Calculate the power being delivered by the each voltage and current source in Figure 2. Source Power Delivering/Absorbing 10V -65.0W Delivering 2.5A -23.8W Delivering 4A -134.W Delivering 3. Calculate the power being delivered by each current source in Figure 3. Source Power Delivering/Absorbing 5mA -121. mW Delivering 2mA -54.8 mW Delivering 4. Using Figure 4 , find the power delivered or supplied by the 10V source. P 10V = -8.40 mW (8.40mW delivered) 5. Calculate the power being delivered or absorbed by the voltage sources in Figure 5 . Source Power Delivering/Absorbing 8V -14.4W 14.4 W delivered 3V 14.4W absorbed 6. Find the power absorbed by each resistor in Figure 6 . Resistor Power 10 Ω 0 W 40 Ω 160. W 20 Ω 80.0 W 7. Prove that power is conserved in Figure 7. W 400 P P absorbed delivered = = ∑ ∑ Exam 2 Practice Problems 8. Find the power being delivered by the 5-A source in Figure 8. P 5A = -95.5W (95.5W delivered) 9.
