Unformatted text preview: 227 Derfte Eq.2.25. Hint: Use Eqs (3) and (4) fiorD Example 2.11 to express iE as a function of is. Solve Eq. (2) for i, and substitute the result into both Eqs. (5) and (6). Solve the "new" Eq. (6) for tr and subshtute this rcsult into tle "new" Eq. (5). Replace tr in the "new" Eq. (5) and solve for is. Note that because rcc appears only in Eq. (1), the solution for is involves the manipulation of only five equatiofls. 2r9 Find (a) t,, (b) ir, and (c) i, in the circuit in Eg. P2.29.
