Name __solution____________ ECE 240 – Quiz #1 January 28, 2010 For the circuit shown above, find: a. i b. v c. the power delivered by the box “A” d. The power delivered by the 2V source e. The power delivered to the 4A source a. KCL at the node to the right of Box A: i+3+4 = 0 i = -7 b. the voltage across the right 2 Ω resistor is 2(3) = 6V with the positive on the bottom.

Unformatted text preview: Thus writing KVL around the outer loop: 2 + 6 – v = 0 v = 8 c. –iv = -(-7)(8) = 56W d. the left 2 Ω resistor has 1A going down, thus the current going down in the 2V source is 7 – 1 = 6A power delivered by the 2V is -6*2 = -12W e. 4(6) = 24W (the current enter the plus side of the voltage) +-!" ! ! #$ ! ! %$ & ’ ) * $...
