Name______________________ Quiz 13 1. Find E o in terms of E i . The equivalent resistance for R 3 in parallel with R 4 is 1/R e = 1/R 3 + 1/R 4 = (R 3 + R 4 )/R 3 R 4 , so R e = R 3 R 4 / (R 3 + R 4 ). I 1 = 0, so E + = 0. E - = E + = 0 I 2 = (E i – E - ) / R 2 = E i / R 2 I e = I 2 E - – E o = 0 – E o = I e R e = I 2 R e = (E i / R
