Step 1 of 2 1.021E Refer to Figure E1.21 in the textbook. Apply Kirchhoff's current law at node B in Figure E1.21. ib=ix (1) Apply Kirchhoff's current law at node E in Figure E1.21. ...... (2) Apply Kirchhoff's voltage law to the loop BEGB. Substitute for and ix for if Therefore, Step 2 of 2 Calculate the input resistance between the terminals B and G. Thus, the input resistance, between terminals B and G is
