07(ba2139 f12-1) (you lose one point for incorrect tutorial section information) Test 1 answer all questions (non-programmable calculators allowed) Question 1 [10 points: determine the th venin equivalent circuit at terminals a-b, [2 points] calculate. Turning off the sources in the circuit, the equivalent resistance seen from a and b equals rth , Rth=req= [((1+1) || 2) + 1] || 2= 1 k : [3 points] calculate thv using node-voltage analysis. 2 v: [3 points] calculate thv using mesh-current analysis. 2: [3 points] assume resistor rl is connected to the terminals a and b. Calculate the current passing through rl while it is absorbing the maximum power from the circuit (imax ). while rl is absorbing the maximum power: rl = rth =1 k imax = In the circuit below, all resistances are in k : [8 points] using superposition method, find two proportionality constants of the circuit, i. e. k 1.
